Defending Your Dissertation: A Guide

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

Oral Examinations

If you have questions about oral examinations, contact us at [email protected] .

Once your dissertation is nearing completion, it’s time to schedule your defense—your final oral examination.

You should begin making arrangements for your defense at the beginning of the semester (especially during the summer) in order to accommodate the schedules of your committee members.

Students must be currently enrolled in the dissertation course for the semester in which the defense is scheduled and held.

Committee Changes

Any changes to your dissertation committee must be approved by the Dean of the Graduate School. Changes should be approved at least 30 days prior to the date of the oral examination so that all new members have ample time to become familiar with your dissertation.

Defense Attendance

You, the student, and your supervisor, in negotiation with the dissertation committee members, should determine a time and date for the defense. Each member of your committee must receive a copy of your dissertation at least four weeks prior to your dissertation defense date. A defense cannot be held within two weeks of the last class day of the semester, unless the committee has consented to hold the defense within those last 2 weeks.

Request for Final Oral Examination Form

You must schedule the dissertation defense with the Graduate School at least two weeks prior to the defense date by completing the Request for Final Oral Examination form. All members of your committee must sign your request form indicating their intent to be present at your final oral. Your graduate adviser must also sign this form to indicate you have been approved to defend.

It is expected that all members of the committee attend the defense. The Graduate School does not distinguish between physical attendance or electronic/virtual attendance of the defense. One non-supervisory committee member may be absent from the defense in if necessary, but all members must read the dissertation and, when satisfied, sign the Report of Dissertation Committee form.

Contact for Questions

Email the Graduate School at the link above with any questions concerning defense attendance.

Format Check Requirements

When you submit the Request for Final Oral Examination form to the Graduate School, you should include one copy each of the dissertation abstract, title page and the committee membership page for a format check in separate PDF. You do not need to include the instructions page.

After the Defense

The official recommendation of your committee and your program is communicated to the Graduate School on the Report of Dissertation Committee. The Dean of the Graduate School depends on this document to determine your eligibility to receive the doctoral degree so it is essential that it be completed and returned in a timely fashion. A passing report signifies that your committee unanimously agrees that you have completed a dissertation that is an independent investigation in your major field.

In the event that revisions to your dissertation are necessary before your committee members approve your dissertation, the report will be retained by your supervisor until all revisions have been completed. After successful completion of your defense and any required revisions to your dissertation, the Report of Dissertation Committee should also be signed by all members of your committee and must be submitted to the Graduate School.

After you’ve made required or requested revisions to your dissertation, if any, check it carefully for grammar, spelling, punctuation, content and format, then convert it to the required PDF format and upload it.

Do not submit your report/thesis/dissertation via email . Final reports, theses and dissertations MUST be uploaded to the Texas Digital Library before your final paperwork and pages will be reviewed. After submission, no revisions or corrections will be allowed except for those required by the dean of the Graduate School.

Upcoming Oral Examinations

Doctoral students’ final oral examinations are open to all members of the University community and the public unless attendance is restricted by the Graduate Studies Committee. Scheduled oral examinations are published on the UT Grad School website.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

• What is your study about and why did you choose to research this in particular?
• How did your research questions evolve during the research process?
• How did you decide on which sources to include in your literature review?
• How did you design your study and why did you take this approach?
• How generalisable and valid are the findings?
• What were the main shortcomings and limitations created by your research design?
• How did your findings relate to the existing literature?
• What were your key findings in relation to the research questions?
• Were there any findings that surprised you?
• What biases may exist in your research?
• How can your findings be put into practice?
• How has your research contributed to current thinking in the field?
• If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

Need a helping hand?

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

• What exactly were you asking in those questions, and what did your research uncover concerning them?
• Which questions were well answered by your study and which ones were lacking?
• Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future. This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

8 Top Tips for Crushing Your PhD Oral Defense

3-minute read

• 27th January 2016

Once you’ve submitted your PhD dissertation , most of the hard work is done. The one big thing standing between you and your shiny new doctorate is your oral dissertation defense .

The exact format this takes will depend on your grad school, but the general idea is that you present your thesis to a committee who have read your dissertation. The committee members then ask questions about your work , which you have to defend to prove your academic credentials. You may be asked to make revisions to your dissertation based on the discussion.

This might sound a bit like a scholastic Spanish Inquisition , but as long as you prepare thoroughly, your oral defense doesn’t have to be a stressful experience:

1. Ask Around

The first thing to do when preparing for your oral defense is to ask your PhD advisor what to expect and check your grad school’s requirements. You could also ask colleagues who have already completed their defense.

2. Practice Makes Perfect

If you get the chance, sit in on other people’s oral defense sessions. Even better, if you have some willing friends available, try practicing your defense presentation in front of them, including having them ask you questions.

3. Re-read Your Dissertation

You don’t have to memorize every detail, but re-familiarizing yourself with your work before your oral defense is definitely a good idea.

4. Arrive Early

On the day, make sure you know where and when your oral defense is scheduled to take place. Get there at least fifteen minutes early so you have time to set up and settle down.

5. Your Thesis Statement

Make sure you have a clear thesis statement to begin your presentation. This will usually include the problem you’re addressing, why it’s important and what your research has achieved.

6. Use Visual Aids

Having handouts or a PowerPoint slideshow to accompany your talk is pretty much standard these days and can enhance your presentation.

7. Don’t Fear the Committee

It’s easy to feel like the committee members are out to get you once the questions start flying, but try not to panic. It’s perfectly fine to ask for clarification if you’re unsure about something.

Likewise, be honest if you don’t have an immediate response; it’s far better to say you’d need to do more research before answering than it is to try and bluff your way through the conversation.

Similarly, don’t feel like you have to rush. Taking a moment to think before answering a question will help you to formulate a considered answer.

8. Believe in Yourself!

The most important thing to remember is that your advisor will not have let you submit your dissertation unless they thought it was a good piece of work. As such you have every reason to be confident, which will make your presentation more convincing. Try to dress smart too, as you want to make a good first impression.

Once you have submitted your dissertation, you may be asked to do a defence of your dissertation. This could be in the form of an oral presentation, a poster presentation of your findings, or you could be invited to a viva voce. Vivas, as they are usually known, are particularly common for research degrees such as MPhils or PhDs and are essentially a verbal defence of your thesis that is conducted in an interview style format. At a minimum, the viva is a way of checking you authored the thesis yourself and understand the detail, but it is also an opportunity to discuss your research findings and interpretations in depth with experts. Preparation is key for defending your thesis in a viva or a presentation format. With a bit of groundwork, you could even enjoy the discussion, after all the thesis is the culmination of all your hard work, and no one knows it better than you.

[Part of the Policies of the CHD, last updated fall 2021]

Dissertation

The dissertation must represent an original and significant contribution to knowledge.  The dissertation should be a coherent document conforming with the customary standards of scholarly discourse and addressed to a broad audience in the corresponding subject rather than to a narrow audience of specialists in the field.  SEAS does not follow the practice in which a collection of manuscripts published or intended for publication as technical papers constitutes an acceptable dissertation.  It should be understood, however, that the student has an obligation to prepare the work for publication in the archival literature in timely fashion.  The dissertation must meet the GSAS requirements available at https://gsas.harvard.edu/degree-requirements/dissertations/formatting-your-dissertation  .

Final Oral Exam ("Defense")

The last two requirements are the final Ph.D. oral examination and an electronic copy of the dissertation submitted as a PDF file.  The student must deliver a complete penultimate draft of the dissertation (except for the acknowledgments) to all members of the research committee at least two weeks prior to the final examination. Once the student has agreed upon a time for the examination with all members of the research committee, the student is responsible for contacting the Office of Academic Programs ( [email protected] ) at least two weeks in advance in order to prepare the exam paperwork, and, if needed, to schedule a room.

The final oral exam (i.e., the defense) is the culmination of a student’s years of effort and formally marks the candidate’s entry into the community of scholars .   As such, the candidate and committee should strive to meet together in person for the exam.  If after attempting to schedule a time for the full committee to meet together in person it appears that no such time can be found, the candidate should consult with the Office of Academic Programs about alternatives, possibly including that one or more committee members attend remotely.

SEAS encourages candidates to provide a videoconferencing (e.g., Zoom) option for remote attendance by guests, community members and the public who may not be able to attend in person.

The final examination is essentially a presentation and defense of the dissertation, though more general questions relating to the field of the dissertation are in order.  At the end of the examination, the research committee may accept the dissertation, possibly subject to agreed-upon revisions, or specify further requirements.  If other than minor revisions are involved, the nature of the conditions that need to be met should be reported to the DGS.  The research advisor must certify in writing that these conditions have been met before award of the degree can formally be recommended by the Dean. 

SEAS facilities are the usual location for the final defense.  A student planning a defense to be held outside of SEAS must have the approval of all their committee members before finalizing the location of the defense. Arrangements as to location will be made by the student through the Office of Academic Programs. Public notice will be given.  The Office of Academic Programs strongly encourages students to schedule their defense not later than two weeks before the GSAS Ph.D. Dissertation submission deadline.

What are the expectations of committee members.

Choosing the dissertation committee is one of the most important decision for a research student. However, putting your dissertation committee becomes easier once you understand the expectations of committee members.

The basic function of your dissertation committee is to guide you through the process of proposing, writing, and revising your dissertation. Moreover, the committee members serve as mentors, giving constructive feedback on your writing and research, also guiding your revision efforts.

The dissertation committee is usually formed once the academic coursework is completed. Furthermore, by the time you begin your dissertation research, you get acquainted to the faculty members who will serve on your dissertation committee. Ultimately, who serves on your dissertation committee depends upon you.

Some universities allow an outside expert (a former professor or academic mentor) to serve on your committee. It is advisable to choose a faculty member who knows you and your research work.

How to Choose a Dissertation Committee Member?

• Avoid popular and eminent faculty member
• Choose the one you know very well and can approach whenever you need them
• A faculty member whom you can learn from is apt.
• Members of the committee can be your future mentors, co-authors, and research collaborators. Choose them keeping your future in mind.

How to Prepare for Dissertation Defense?

1. Start Your Preparations Early

Thesis defense is not a 3 or 6 months’ exercise. Don’t wait until you have completed all your research objectives. Start your preparation well in advance, and make sure you know all the intricacies of your thesis and reasons to all the research experiments you conducted.

2. Attend Presentations by Other Candidates

Look out for open dissertation presentations at your university. In fact, you can attend open dissertation presentations at other universities too. Firstly, this will help you realize how thesis defense is not a scary process. Secondly, you will get the tricks and hacks on how other researchers are defending their thesis. Finally, you will understand why dissertation defense is necessary for the university, as well as the scientific community.

3. Take Enough Time to Prepare the Slides

Dissertation defense process harder than submitting your thesis well before the deadline. Ideally, you could start preparing the slides after finalizing your thesis. Spend more time in preparing the slides. Make sure you got the right data on the slides and rephrase your inferences, to create a logical flow to your presentation.

4. Structure the Presentation

Do not be haphazard in designing your presentation. Take time to create a good structured presentation. Furthermore, create high-quality slides which impresses the committee members. Make slides that hold your audience’s attention. Keep the presentation thorough and accurate, and use smart art to create better slides.

5. Practice Breathing Techniques

Watch a few TED talk videos and you will notice that speakers and orators are very fluent at their speech. In fact, you will not notice them taking a breath or falling short of breath. The only reason behind such effortless oratory skill is practice — practice in breathing technique.

Moreover, every speaker knows how to control their breath. Long and steady breaths are crucial. Pay attention to your breathing and slow it down. All you need I some practice prior to this moment.

6. Create an Impactful Introduction

The audience expects a lot from you. So your opening statement should enthrall the audience. Furthermore, your thesis should create an impact on the members; they should be thrilled by your thesis and the way you expose it.

The introduction answers most important questions, and most important of all “Is this presentation worth the time?” Therefore, it is important to make a good first impression , because the first few minutes sets the tone for your entire presentation.

7. Maintain Your Own List of Questions

While preparing for the presentation, make a note of all the questions that you ask yourself. Try to approach all the questions from a reader’s point of view. You could pretend like you do not know the topic and think of questions that could help you know the topic much better.

The list of questions will prepare you for the questions the members may pose while trying to understand your research. Attending other candidates’ open discussion will also help you assume the dissertation defense questions.

8. Practice Speech and Body Language

After successfully preparing your slides and practicing, you could start focusing on how you look while presenting your thesis. This exercise is not for your appearance but to know your body language and relax if need be.

Pay attention to your body language. Stand with your back straight, but relax your shoulders. The correct posture will give you the feel of self-confidence. So, observe yourself in the mirror and pay attention to movements you make.

9. Give Mock Presentation

Giving a trial defense in advance is a good practice. The most important factor for the mock defense is its similarity to your real defense, so that you get the experience that prepares for the actual defense.

10. Learn How to Handle Mistakes

Everyone makes mistakes. However, it is important to carry on. Do not let the mistakes affect your thesis defense. Take a deep breath and move on to the next point.

11. Do Not Run Through the Presentation

If you are nervous, you would want to end the presentation as soon as possible. However, this situation will give rise to anxiety and you will speak too fast, skipping the essential details. Eventually, creating a fiasco of your dissertation defense .

12. Get Plenty of Rest

Out of the dissertation defense preparation points, this one is extremely important. Obviously, sleeping a day before your big event is hard, but you have to focus and go to bed early, with the clear intentions of getting the rest you deserve.

13. Visualize Yourself Defending Your Thesis

This simple exercise creates an immense impact on your self-confidence. All you have to do is visualize yourself giving a successful presentation each evening before going to sleep. Everyday till the day of your thesis defense, see yourself standing in front of the audience and going from one point to another.

This exercise takes a lot of commitment and persistence, but the results in the end are worth it. Visualization makes you see yourself doing the scary thing of defending your thesis.

How to prepare an excellent thesis defense

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

Dissertation Defense

What is a dissertation defense?

The final oral examination for a doctoral candidate, commonly known as the dissertation defense, represents the conclusive formal stage prior to the submission of the dissertation manuscript and the conferral of the doctoral degree. This examination centers on the dissertation itself and its relevance within the candidate's area of academic specialization.

A successful defense is the peak of your academic career, so don’t treat it lightly. Make sure that you take enough time to learn everything there is to know about the topic and prepare well. If you look at your paper and it seems raw or unfinished, and especially if your academic advisor says so, it might be best to take another semester for prep. We don’t mean to scare you, but it truly is a responsible moment, and if you fail your defense, all the years of hard work will be wasted.

Defending doctoral dissertation is not going to be easy. If you don’t get to choose the members of your board and you will be met with unfamiliar faces, you might start to panic and feel lost. This is exactly why you need to be over-prepared. In fact, there’s no such thing as being overly prepared when it comes to your defense. Think of all the possible questions your dissertation committee members may have, even the most far-fetched ones, and then find the answers.

Doctoral dissertation defense process

During the dissertation defense, the candidate delivers an oral presentation of their dissertation to the Supervisory Committee (refer to the Supervisory Committee Policy) and to a public audience. The length of both the oral presentation and the subsequent question-and-answer session is determined through consultation between the Committee and the candidate, ensuring it meets the specific requirements and standards of the process.

The dissertation defense process, often the culmination of a doctoral program, is a critical step in the journey towards earning a PhD or similar advanced degree. This process involves several key stages designed to assess the quality, originality, and contribution of the candidate's research. Here's a general overview:

• Completion of the Dissertation : Before the defense can be scheduled, the dissertation must be completed. This involves conducting original research, writing up the findings, and often, revising the document based on the advisor's feedback.
• Submission of the Dissertation : Once the dissertation is completed and approved by the advisor, it must be submitted to the department or dissertation committee for review. This submission typically includes a written document detailing the candidate's research findings and conclusions.
• Scheduling the Defense : After the dissertation is submitted, a defense date is scheduled. The timing of this can vary widely depending on the institution and the specific requirements of the department.
• Preparation for the Defense : The candidate prepares a formal presentation of their research findings. This presentation is typically structured to highlight the research question, methodology, key findings, and the significance of the work.
• The Defense Event : The defense itself is a public forum in which the candidate presents their research to the dissertation committee and often, an audience of peers, faculty, and sometimes the general public. Following the presentation, committee members and sometimes audience members ask questions related to the research and the findings.
• Question and Answer Session : This session allows the committee to probe the candidate's understanding of the research area, methodology, and conclusions. The candidate must defend their research choices and conclusions, demonstrating deep knowledge of the subject.
• Committee Deliberation : Following the Q&A, the committee deliberates in private to decide whether the candidate has successfully defended the dissertation. Criteria for success can include the originality of the research, the soundness of the methodology, and the significance of the contributions to the field.
• Outcome Announcement : The committee then informs the candidate of the outcome. Possible outcomes can include pass, pass with minor revisions, pass with major revisions, or fail, although specifics can vary by institution.
• Completion of Revisions (if required) : If the committee requires revisions, the candidate must complete these before the degree can be officially awarded. The scope of revisions can vary significantly.
• Final Submission : After any required revisions are made and approved by the committee, the final version of the dissertation is submitted to the university. This often includes submitting bound copies of the dissertation and making it available through the university's library or institutional repository.
• Graduation and Degree Conferral : Following successful defense and submission of the final dissertation, the candidate is eligible to graduate and receive their doctoral degree.

This process is a significant milestone in an academic career, representing the transition from student to scholar and contributing new knowledge to the field.

Even though it may seem horrible and nerve-racking, the process of defending your dissertation is pretty straightforward. And if you take your time to prepare for it well, you will not have any problems with the defense itself.

The scariest part is presenting your work to a group of professionals. You have to show your proficiency in the field, ability to think critically and withstand criticism. Most colleges and universities will allow you to choose your own committee. So, try to take your pick as early as possible so you’re not left with people the rest of your group didn’t want. 

How to defend dissertation?

Navigating your dissertation defense involves thorough prep, including understanding your institution's format, mastering your material, anticipating committee questions, and perfecting your presentation. During the defense, remain poised, address inquiries with depth, and interact professionally. Post-defense, be ready for revisions. Ensure professional attire, early arrival, and confidence in your expertise. Embrace feedback as growth. Celebrate this significant academic milestone, as it's not only an examination but a showcase of your scholarly journey.

Defending your dissertation is a pivotal moment in your academic career. Here's a step-by-step guide to prepare for and successfully defend your dissertation:

Let’s assume that your dissertation paper is done and approved. The next step after choosing your committee would be preparation. In one of the committee meetings, you will discuss how much time you have for your defense and the Q&A session afterward. Normally, the whole defense lasts about an hour, but it can vary depending on the number of doctoral students defending on the same day. 

Preparing for your defense means getting thoroughly acquainted with your paper. It might seem like a ridiculous piece of advice if you’ve written it yourself, yet, with a paper of that size, it’s easy to get lost. If you’ve used a dissertation writing service , you need to take special care in learning the contents of your paper. 

Prepare a presentation that you will be showing to the committee. Make sure the slides are clear and easy to understand, with most information placed in the speaker notes. You don’t want to overload the slides with text. 

Analyze your dissertation and think of all the possible questions the defense board members may have afterward. It’s hard to anticipate what a professional may ask about your ‘rookie’ paper, so it might help to speak to your academic advisor before the PhD defense . They might shed some light on the inconsistencies and possible lack of analysis in some areas. 

How to prepare for defense day?

When the day of defending dissertation finally comes, no matter how prepared you are, it will still be stressful. So, it makes sense to come over-prepared. Learn your dissertation text by hard.

Find every grammatical mistake and fix it. Get acquainted with every letter and word and really make sure it’s perfect. If you are convinced your paper is perfect, it will be hard for the defense board to convince you otherwise. 

How do I know I’m ready for my PhD dissertation defense?

Your academic advisor is your best friend in this situation. They have lots of experience in the matter, and they will be the first person to tell you if your paper is defense-proof. If you see them doubting or if they are asking lots of questions, use those questions as learning points. 

Most likely, they criticize you not because they hate you. But because they want to show you your gaps in knowledge. This is a powerful tool to help you find blank spots and fill them

What should I bring to my PhD thesis defense?

• Presentation Materials : This includes any slides or visual aids you'll use to support your talk. Ensure they are ready and compatible with the equipment available.
• Laser Pointer : Useful for highlighting specific areas or data on your slides during the presentation.
• Copy of Your Dissertation : Have at least one printed copy for your own reference. It's helpful for addressing specific questions or sections during the Q&A.
• Pen or Pencil : For making quick notes or annotations based on feedback or questions you may receive.
• Notepad : To jot down notes, questions, or reminders during the defense.
• Bottle of Water : Keeping hydrated is important, especially since you'll be speaking for an extended period.
• Backup of Your Presentation : Have a backup on a USB drive or accessible online in case of technical difficulties.
• Any Necessary Forms : Sometimes, there are forms that committee members need to sign post-defense. Check with your department for any such requirements.
• Questions for Your Committee : Have a list of questions or clarifications you might want to ask your committee after your defense.
• A Watch or Timer : To keep track of your presentation time and ensure you cover all points within the allotted duration.

Depending on how long is a PhD defense, you will need a different supply. If you are planning to sit through your whole class’ defense, you will need lots of water, some snacks to eat during the breaks, and your presentation materials.

However, if you are allowed to only show up to your defense and not listen to the entire class defend their dissertations, the most important thing you need to have is your dissertation and presentation. And don’t forget to bring some water, it can help you calm down if you get stressed.

Why does the dissertation length vary?

Various elements, such as institutional standards, the research's complexity, the extent of analysis, and the presence of supplementary materials, can determine a dissertation's length.

The length of your defense may also depend on how long is a dissertation . If your dissertation is 70 pages, your defense will definitely run shorter than if it is 300 pages long. The length of your paper will also influence the length of your PowerPoint presentation and the number of questions you get.

But how do you defend a dissertation? Defense is just an academic word for presenting your findings. You do your research, you present it to the board, and they ask you questions. By answering these questions, you defend the legitimacy and academic value of your doctoral defense research.

The key here is preparedness. Being well-acquainted with the contents of your paper and being able to defend it is your key to success. If you’re not sure about some parts of your dissertation, consult your academic advisor. They will be willing to help and advise you on whether you should take another semester to prepare.

Of course, it’s a great thing that ‘ write my dissertation ’ services exist. You can address a service like Studyfy and rely on it completely in the dissertation writing process. If you do, you can order your dissertation chapter by chapter and bring each draft to the professor for their notes and critiques.

What else do I need to know?

The most important part is you need to be prepared to defend dissertation meaning, and you need to know your dissertation by heart and be ready to justify every word in it. Sure, it may sound terrifying but thinking that millions of people have done that before you might give you some ease. 

How long is a dissertation defense?

Normally, defending my dissertation shouldn’t take more than an hour and a half. It usually lasts anywhere between 30 minutes and 1,5 hours.

It depends on your academic level, the number of people defending, and your preparedness. If the committee members sense you’re ill-prepared, they will ask you more questions.

It’s not because they want to thank you, but actually because they want to give you more chances. Asking more questions is usually an attempt to find an area that you’re very good at to give you a chance to redeem yourself.Your doctoral defense ia an important part of your doctoral journey, and it's bound to be more intense than a bachelor’s one. That’s only natural. Since your doctoral dissertation will be more in-depth, show a deeper understanding of the subject and better proficiency. 

The length of your defense will depend on many factors. But the most important one is your preparedness and confidence. If you are not prepared well, the dissertation committee will ask you lots of questions. They do that to find an area of study that you are good at, but at that moment, it might make you even more stressed. So, coming prepared is the best thing you can do for your defense to be successful. 

Using services like Studyfy is also an option. Yet, you must understand that if you show up with a perfectly written paper, yet you have no idea what it’s about, it will raise even more questions. That’s why you must prepare very well, regardless if you write your paper yourself or outsource it. If you still have some questions about how to write a dissertation , make sure to read our guide.

What is the key to dissertation defense?

Comprehensive Preparation: Familiarize yourself with your institution's defense protocols and engage in extensive practice. Segment your thesis for easier presentation, manage timing, highlight essential arguments, and anticipate likely inquiries. Organize a practice defense session to gain comfort with the procedure.

The most important thing you need to do to defend my dissertation is to start your prep early enough. What does it mean to defend your dissertation? Your defense is the pinnacle of all the hard work you've put in your studies throughout the years. Every time you write a paper, you must understand that you may use that research for your dissertation. So, your prep for dissertation defense starts as soon as you enter college.

What is defending a dissertation? Are there dissertation committee members?

Defending dissertation meaning is the process of presenting your research and findings to the board. Regardless if you buy dissertation or write it yourself, you will need to defend it. This is why you need to prepare carefully for your defense - study your paper through and through, think about all the possible questions you may be asked and think of the answers.

The dissertation committee or the dissertation chair are faculty members that will simply ask dissertation defense questions - some about research methodology, and some about the primary role of your work. Before the actual oral defense, try setting up a mock defense with your friend and go over the important topics.

How long is a thesis defense?

It depends on the length of your paper. Since your master’s thesis will probably be a bit shorter than a doctorate dissertation, you can count on your oral defense lasting up to an hour. Again, the length of the doctorate defense depends on how well you are prepared and how you handle the professors’ questions.

Division of graduate studies menu, division of graduate studies, doctoral oral defense procedures, the information on this page pertains to doctoral students only. master's students may or may not be required to hold a defense of their thesis or project; confer with your department for more information. , preparing for the oral defense.

All doctoral students must hold a formal public defense of their dissertation on a date that is acceptable to the dissertation committee. Defenses may take place on any date, but in order to graduate in a given term, a student must defend on or before the deadline for that term . The defense should be held on campus whenever possible, but remote defenses are also allowed (see Attendance Policies below). 

Students are expected to provide the committee with a full draft of the dissertation at least 3 weeks prior to the formal defense. It is also generally expected that the committee has tentatively approved the dissertation prior to the defense. 

If the committee has any reservations about the acceptability of the dissertation, aside from minor revisions that may be discussed at the defense, it is recommended that the defense be postponed until such time as the committee is generally in agreement the defense will be successful.  

To graduate in a given term, the oral defense must take place by Friday of week 9 of that term.

The student is expected to provide the committee with a full draft of the dissertation at least 3 weeks before the defense date .

The deadline to apply for oral defense is 2 weeks before the defense date.

The committee must log in to GradWeb and certify the results of the defense  within 2 weeks after the defense. 

The final, committee-approved dissertation must be uploaded   within 2 weeks after the defense.

• Current Students
• Final Doctoral Exam

Doctoral Exam Guide

Final oral defence, purpose of the final oral defence.

• To ensure that the candidate is able to present and defend the dissertation and its underlying assumptions, methodology, results, and conclusions in a manner consistent with the doctoral degree being sought;
• To communicate the results of the work to the campus community.

Structure of the Final Oral Defence

The detailed Final Oral Defence procedures are outlined in the Exam Instructions . A copy of these instructions is provided to the examining committee approximately one week before the Oral Defence.

The basic structure of the Oral Defence is:

• Candidate makes a public presentation of the dissertation (maximum 30 minutes)
• Examining committee members question the candidate
• Members of the audience are invited to ask questions of the candidate
• Examining committee holds an in-camera discussion where it decides on the overall recommendation it will make to Graduate and Postdoctoral Studies (see Evaluation Protocol below)
• Chair conveys the recommendations of the examining committee to the candidate

Candidates are encouraged to arrive 30 minutes early to get comfortable and set-up in the exam room. Exams start promptly at the official start time. The doors to the exam room are closed at the start of the exam and no one may enter the exam room, either physical or virtual, once the Final Oral Defence has begun. The Oral Defence usually takes two to two and a half hours.

Audiovisual Equipment

The examination rooms in the Graduate Student Centre come equipped with a projector and screen (room 200) or a large monitor and auxiliary screen (room 203), a white board, and a podium. Most candidates prefer to bring their own laptops to the examination; it is possible to use the wall mounted PC in either room, in which case candidates should either have their presentations available on cloud storage or bring a thumb drive.

The displays in rooms 200 and 203 are equipped with VGA and HDMI inputs. Candidates using laptops without these outputs must bring the appropriate adaptors.

Candidates planning to use Zoom to enable remote attendance should indicate their preference when making the exam booking.

Language Requirement

Candidates for the Final Doctoral Examination must have fulfilled all course and/or language requirements of the degree program. It is the responsibility of the candidate's graduate program to ensure these requirements have been met, and that the candidate's oral language proficiency is adequate for full communication between the examination committee and the candidate.

The Final Doctoral Examination is a public event at UBC and as such will be conducted in English. The candidate's oral proficiency in the language of the examination must be adequate for full communication between the examination committee and the candidate. For theses in language programs, some questions can be posed or answered in the language concerned, provided the examination committee can follow proceedings (by translation if necessary) in this other language.

Remote Attendance at in-person Exams

For information regarding Virtual Defences held entirely on Zoom, see Schedulng the Oral Defence, and the Virtual Exam Protocol .

Managing remote attendees can pose both technological challenges and challenges for candidates in managing divided attention. For these reasons, Hybrid Defences with more than one remote attendee should be discussed with the doctoral exams team in advance. We will work with candidates and supervisors to make sure these defences run smoothly .

Normally, examiners required for quorum at an in-person defence should be physically present in the room. The external examiner or a third member of the supervisory committee may attend the defence remotely. 

Doctoral exams team use a Meeting OWL to support videoconferencing with Zoom. Candidates who wish to have remote attendees should indicate this on their Booking Request. The OWL can be used in either room.

For exams in other suitable rooms on campus, the research supervisor should verify that appropriate equipment is available in the room. Devices such as an OWL, or other mobile AV device may be used.

Should any technological issues arise during the course of the exam, the exam may be paused for a reasonable amount of time to resolve them. Only those examining committee members who have been present for the full duration of the exam can cast a vote in the proceedings. If members required for quorum lose connection and it cannot be restored, the exam will need to be rescheduled.

Please also note that the examination chair has the right to discontinue a remote connection if it is interfering with the proper conduct of the examination.

Attendance of the External Examiner

The external examiner's participation in a candidate's Final Oral Defence offers the opportunity for a valuable dialogue about the dissertation and the research it presents. Therefore, the participation of the external examiner in the Final Oral Defence is encouraged, but it is not required.

Inviting the external examiner to participate in the Final Oral Defence is at the discretion of the research supervisor; Graduate and Postdoctoral Studies will not extend such an invitation. For information about inviting the external examiner, please see Scheduling the Oral Defence .

Recording the Examination

See Recording the Examination .

Evaluation Protocol for the Oral Defence

The examining committee is asked to make an overall recommendation after evaluating two aspects of the candidate's performance:

• The Oral Defence : The committee should evaluate the candidate’s performance while presenting the synopsis, responding to questions, and defending the work. The committee must decide whether or not the performance met the standard of excellence expected of a doctoral candidate at UBC.
• The Dissertation: The committee should evaluate the overall merit of the dissertation, considering scholarship, scope and impact of the contribution made, and the quality of writing. They are asked to take into consideration the external examiner’s report, the assessments of the other examining committee members, and candidate's responses to questions during the Oral Defence. The committee will decide what revisions, if any, will be required before the dissertation can be considered fully acceptable.

Evaluation options available to the examining committee are:

• No revision or only minor revisions are required. The committee charges the research supervisor to verify that the required changes have been made.
• Substantive revisions are required. The committee chooses two or more of its members, including the research supervisor, to verify that the required changes have been made.
• The dissertation is unsatisfactory. Major rewriting and rethinking are required.
• The dissertation is unacceptable; it is fundamentally flawed and therefore beyond revision.

The examining committee is then asked to select one of the following overall recommendations:

• Pass. Pending final submission of the dissertation to the Faculty of Graduate and Postdoctoral Studies, the University should award the doctoral degree to this candidate.
• Re-examination required. The candidate should be allowed a second attempt to pass the Final Doctoral Examination. (No more than one subsequent attempt is permitted.)
• Fail. The University should not grant the doctoral degree to this candidate.

In any category where the committee's judgment is unanimous, or nearly so (in that at most one examiner dissents), the chair will express it using the check-boxes on the chair's Report form. Dissenting opinions will be noted in the text of the Chair’s Report. In any category where two or more examiners disagree with the majority view, the chair will select a box labelled “No Decision” and provide a written description of the differing views in the text of the report. If this occurs, the chair will inform Graduate and Postdoctoral Studies as soon as possible (typically within one business day of the examination). The Dean of Graduate and Postdoctoral Studies will review the Chair's Report and promptly determine an appropriate course of action, in consultation with the examination chair and the examining committee.

The examination chair is responsible for completing the Chair's Report form and submitting it to Graduate and Postdoctoral Studies within one week of the Oral Defence.

Section 10: PhD Dissertation Defense: Final Oral Examination Overview, Committee, and Process

​​​​​​10.1 composition of the final oral examination committee & process.

The dissertation committee will consist of at least three graduate faculty members, including at least one core BME departmental faculty member, and will be chaired by the research advisor, who must have level-P graduate faculty status in BME. Soon after passing candidacy, students should obtain official approval of a dissertation committee by emailing a brief request, addressed to the BMEGSC, to the Graduate Studies Coordinator at [email protected] . For most students, this simply will be the candidacy committee minus one member. These three BMEGSC-approved dissertation committee members plus one assigned Graduate School Representative comprise the final oral examination committee. Petitions to add external, non-voting members must be completed via gradforms.osu.edu. Students should be sure to work closely with members of their dissertation committee.

It is the student's responsibility, with the approval of the research advisor, to contact all examiners on the dissertation committee and schedule the final oral examination (also called the dissertation defense). Typically the student provides committee members with a dissertation draft when doing this. Students also must take a copy of their dissertation draft to the Graduate School for a required formatting review. When the date and time for the dissertation defense are arranged, students may schedule a room for a 2-hour block of time in BME or elsewhere on campus if it is more convenient for the committee. (Under normal circumstances, a teleconferenced exam would require a petition; due to COVID 19, all exams are currently required to be teleconferenced via Zoom so no petitions are needed unless for external members.)

The final oral examination committee will examine the student on the research project and dissertation in accordance with Graduate School regulations and must comply with the deadlines published by the Graduate School at the beginning of each term. The examination should not exceed two hours. Only examination committee members may be present during a BME PhD examination; however, students and faculty may attend presentations given before the exam begins. Students are welcome to advertise their presentations.

The graduate faculty representative is assigned by the Graduate School after the student files the Application for Final Oral Examination. This form is to be submitted by the student to the Graduate School via gradforms.osu.edu and approved by the advisor at least two full weeks before the date of the oral examination. Failure to meet this deadline will result in the rescheduling of the exam. The location (or indication of teleconferencing) and 2-hour time block must be listed. (Note that a copy of the dissertation must be sent to the assigned graduate faculty representative at least one full week before the defense, if not longer.) This application generates a link to the Final Oral Examination Report form, which is sent to the osu.edu email addresses of the final oral examination committee. The committee’s decision is recorded by each committee member via gradforms.osu.edu.

The student is considered to have completed the final oral examination successfully only when the decision of the final oral examination committee is unanimously affirmative. A student must be registered for at least three graduate credit hours during the term in which the final oral exam is held. For information on teleconferencing the doctoral defense in the event that a committee member may need to participate while off-site or petitioning to include an extra or non-voting, non-OSU committee member, please see gradforms.osu.edu. For policies governing the Final Oral Examination rules see the GSH.

 10.2 Dissertation Guidelines

The dissertation should be an original research project that makes a new contribution to the field. Proposals and protocols should be approved by the student’s advisor(s) prior to beginning research. The dissertation must be completed in accordance with Graduate School policies and must comply with the deadlines published by the Graduate School at the beginning of each term. Students may reach out to their lab mates, peers from BMEGSA and/or student mentors for advice on completing the thesis. For Dissertation formatting and submission procedures, see the Graduate School website.

Students are encouraged to read the Graduate School Newsletter for leads on Graduate School and Writing Center workshops on dissertation writing or to schedule a review at the Graduate School ( Graduation Services area) to learn about formatting and electronic document submission. Visit the Graduate School for detailed information on the required format.

If a student fails to submit the final copy of the dissertation document to the Graduate School within five years of being admitted to candidacy, their candidacy is cancelled. In such a case, with the approval of the advisor and the Graduate Studies Committee, the student may request to take a supplemental candidacy examination. If the student passes this supplemental candidacy examination, the student is readmitted to candidacy and must then complete a dissertation or

D.M.A. document within two years. See GSH. Students who do not complete the requirements above within the timeframe may be dismissed from the program.

FINAL ORAL EXAMINATION PLANNING: A SAMPLE TIMELINE

Results for the Defense (Final Oral Examination) and Dissertation must be reported by the Dissertation Committee by Graduate School deadlines. Exam dates should be chosen to meet the deadlines.

• Application to Graduate : Department Deadline - first day of the intended semester; Graduate School deadline - 3 rd Friday of the semester of graduation
• Application for Final Oral Exam : File 3-4 weeks ahead of time to ensure meeting Graduate School deadline of at least 2 full weeks before the actual defense
• Dissertation Formatting check at Graduate School : as early as possible, aligned with the Application for Final Oral Examination
• Send copy of dissertation to Graduate Faculty Representative as soon as one is assigned, no less than one full week before the defense

AFTER THE DEFENSE:

• Make sure your Dissertation Committee completes the Exam Report by posted deadline
• Revise and submit approved Dissertation by posted deadline via Ohiolink
• Make sure your Dissertation Committee completes the Dissertation Approval by posted deadline

10.3 Required Seminar Presentation & Publication Submissions

PhD students are expected to present an open seminar on their dissertation as part of the BME seminar series. To avoid delays in graduation, this should be done at least one or two semesters before graduation is anticipated. It is the student’s responsibility to contact the seminar faculty coordinator to get scheduled before all spaces are filled. In the event that there is a conflict, students may advertise the presentation portion of their dissertation defense to be counted as a seminar presentation, making sure to notify the BMEGSC via email to the graduate studies coordinator. As detailed in the curriculum requirements, PhD students also are expected to have submitted two manuscripts for publication and to have made one oral or poster presentation at a scientific meeting in order to graduate. This information is to be emailed to the graduate studies coordinator when applying to graduate.

10.4 Graduation for PhD Students

In order to graduate with a Doctoral (PhD) degree students must meet all requirements established by the department and the Graduate School. An Application to Graduate must be filed on gradforms.osu.edu no later than the first day of the term in which a student intends to graduate to allow time for a BME graduation audit and approval by the Advisor and Graduate Studies Committee Chair. Graduating students must be enrolled for at least 3 credit hours in the term of graduation. Visit the Graduate School’s graduation checklist for PhD students in their final term of enrollment for more information .  If requirements go unmet or exam or thesis deadlines are missed, students may be able to meet the Graduate School’s end-of-semester deadlines without having to register the following term. If the E-O-S deadlines are missed, it will be necessary to resubmit a new Application to Graduate the following term.

DEGREE COMPLETION REMINDERS FOR PhD

• Students & advisors may jointly petition the BMEGSC for waivers of program or committee requirements. These should be accompanied by a proposed or approved program of study whenever possible.
• Petitions should be submitted in the form of a brief letter addressed to the BMEGSC and sent to [email protected] and will be considered at convened monthly BMEGSC meetings. Last-minute petitions may not be reviewed.
• Changes to an approved Program or Committee must be reviewed by the BMEGSC at least one full semester  before an Application to Graduate is filed.
• Applications to Graduate will not be approved unless the student’s final BMEGSC-approved Program and Committees are on file in the Graduate Office and most other graduation requirements, as stated in the GSH and BMEH, are met.
• Applications to Graduate should be submitted via gradforms.osu.edu at least one full week in advance of the Graduate School deadline. No forms will be signed by the Chair of the Graduate Studies Committee until a graduation audit has been completed by the BME graduate studies office.
• Be sure to build in time for a Graduate School review of the formatting of your dissertation draft.
• Be sure to build in time for any gradforms.osu.edu committee member petitions.
• Review your advising report each semester and contact your faculty about missing/outstanding grades.
• Publication and presentation lists should be emailed to the Graduate Studies Coordinator at [email protected] before the end of the semester in which you plan to graduate.
• Complete the BME assessment graduation survey. (Contact the graduate studies coordinator for the link at [email protected] .)

Tips to ace your doctoral dissertation oral defense.

By Nicole Dhanraj, Ph.D.

Preparing for your doctoral dissertation oral defense can be a challenging but exciting experience. It is exceptionally crucial that you are well prepared for your defense. This is the near-final step in your doctoral academic journey and in some cases, will determine if you finalize, earn and are awarded your doctoral degree!

The dissertation oral defense is an opportunity for you to demonstrate the mastery of your research topic, your understanding of the field, the scope of your research (including what is inside - and not inside, scope) and the ability to communicate your findings effectively to your Chair and committee members. In some cases, your defense will be recorded for others at the university to review as well so you should also get comfortable being on camera.

Defense Expectations

During the dissertation defense, you will provide an overview of your study to demonstrate that you completed a significant piece of original research and that you deeply understand your topic. You will present a brief overview of your research, including the research question, methodology, results, and conclusion. Essentially, in the doctoral dissertation defense, you will walk the committee members and any attending guests through an overview of your five dissertation chapters. However, often in the final defense you are expected to focus primarily on Chapters 4 and 5 as Chapters 1 through 3 have already been addressed, most likely, in your proposal oral defense.

Tips to Ace Your Defense

Here are some tips to help you successfully navigate and ace your doctoral dissertation oral defense:

Stay organized: Make sure your materials, including slides, handouts, and backup data, are organized and ready to present. Be familiar with presenting in presentation mode so that you are not fumbling through your slides. Make sure you practice with the tool your College uses to present! You don’t want to waste the first ten minutes testing microphones and learning how to share your slides.

Practice your presentation: Ensure you rehearse your defense multiple times with friends, peers, or faculty members. This will help you feel more confident, reduce the chances of forgetting essential points, and allow you to work out any kinks and refine areas that need improving. You want to ensure you are communicating effectively and smoothly. It is also a means to identify potential questions that could arise during your defense, although you can also expect questions on methodology that friends and family likely won’t be able to pinpoint. Practicing your presentation helps you become more familiar with your material, which can increase your confidence and reduce nervousness during the actual defense.

Be specific and clear: When presenting your findings, be confident and transparent in explaining the relationship between your research questions and your results. Your committee will look to see that you understand your work and how it contributes to the field. They will also expect that you know what you did not cover, and what the limitations and assumptions of your work are and how they impacted your study. If there was any potential bias, be prepared to talk about it.. Ensure you can address the underlying reasons if you fail to reach your target sample size and whether that impacted the final outcome or not.

Review your work thoroughly: Ensure you are familiar with every aspect of your research and be prepared to defend it. This includes understanding your research methods, results, biases, outcomes, limitations and conclusions. Review your work for spelling and content errors.

Common Defense Questions

Prepare for questions: Anticipate potential questions from your committee and practice answering them. This will help you feel more comfortable and confident during the actual defense. Make sure you clearly understand what you want to learn through your research. You should be able to connect your findings to your research questions and explain how your results answer the questions you set out to answer and support your conclusions. Here are some common questions you may receive from your panel.

• Walk us through your methodology and tell us why this methodology was appropriate for your study.
• How do your findings compare to previous research in the field?
• Can you discuss the limitations of your research and what future directions it suggests?
• What happened as a result of the obtained sample size?
• Is your work generalizable? If so, to what population? If not why?
• Can you describe the process you used to analyze your data?
• How did you address bias in your data analysis?
• Can you discuss the potential future implications of your research?
• How do you plan to disseminate your findings and make them accessible to others in the field?
• Can you discuss the ethical considerations involved in your research and how you addressed them?
• What were the limitations or gaps in the literature?
• Discuss the strengths and weaknesses of the research design you used.

Handling Critiques and Questions

Handling questions raised by the panel during a doctoral dissertation oral defense can be challenging, but some strategies can help you prepare and respond effectively:

Listen carefully: When a panel member asks a question, listen carefully to understand what they are requesting before responding. Take a moment to gather your thoughts and formulate a clear and concise answer.

Be honest: If you don't know the answer to a question, it's okay to admit it. You can also offer to follow up with more information after the defense.

Be prepared: Anticipate the types of questions that may be asked and be ready to provide thoughtful and well-reasoned answers.

Stay calm: Remember that your defense is an opportunity to showcase your hard work and demonstrate mastery of your topic. Stay calm and confident, and be open to constructive criticism. Do your best to answer the questions, and you can state that you do not know the answer to a question if you do not (that is far better than guessing your way through and being incorrect!).

Clarify: If you're unsure what a panel member is asking, don't hesitate to ask for clarification. This shows that you're engaged and invested in the defense process. If you are not understanding the question, just say so. If the question being asked is outside the scope of your research, say so! Rememeber the goal is to show that you know every aspect of your study!

Provide examples: If possible, provide concrete examples to support your answers and help illustrate your points.

Keep your answers focused: When answering questions, keep your responses focused and avoid getting sidetracked. Stay on point and use your time effectively.

Importance of being prepared and confident

Remember that your doctoral dissertation oral defense culminates in years of hard work and dedication. By preparing thoroughly, you can increase the chances a successful outcome and take a significant step towards earning your doctoral degree. By preparing this way, you will be able to effectively communicate the relationship between your research questions, findings, and the literature review, demonstrating your mastery of the topic and ability to contribute to the field, and no doubt finish with your degree in hand!

Degree requirements

Competency requirement.

Students must demonstrate basic competency in three chosen sub-disciplines of chemistry (analytical, biochemistry, inorganic, organic, physical). Competency is established in one of the following ways: Scoring at the 50th percentile level (national norm) on the proficiency exam, completing a one-semester review course with a grade of C or better (courses specified below), or completing a one-semester graduate-level/advanced course in that sub-discipline of chemistry with a grade of B or better. The competency requirement must be fulfilled before the beginning of the student's third semester in the graduate program.

Review courses

Courses currently designated as review courses are:

• CHEM:4171 (formerly 4:171): Advanced Analytical Chemistry
• BIOC:3120 (formerly 99:120): Biochemistry and Molecular Biology I
• CHEM:4270 (formerly 4:170): Advanced Inorganic Chemistry
• CHEM:4372 (formerly 4:172): Advanced Organic Chemistry
• CHEM:4431 (formerly 4:131): Physical Chemistry I

Advanced course requirement

Beyond the competency requirements, a minimum of four additional courses that total at least 11 semester hours of graduate credit must be completed by the end of the fourth semester in residence. Grades of "B" or higher must be attained in all of these advanced courses. A grade of "B-" does not meet this requirement. Research, seminar, and pedagogy credits, courses that are doubly listed with sub-100 level numbers, courses taken with the S/U grade option, and courses with grades of "B-" or lower cannot be used to fulfill this requirement. The student is strongly encouraged to develop a detailed course plan that is reviewed and approved by the research advisor.

Comprehensive examination

The oral comprehensive examination is designed to assess the student's overall progress, knowledge of fundamental chemical principles and chosen area of specialization, and general competency for PhD research.

Before the beginning of the second semester after a permanent advisor has been appointed, a Graduate Academic Committee (GAC) of five faculty, at least four from Chemistry, will be formed for each student with a PhD degree objective. The committee will consist of the research advisor and four additional members invited by the student subject to the advisor’s approval.

The five member committee for the comprehensive examination is the same as the student's Graduate Academic Committee (GAC). Additional faculty members may be invited to attend the oral comprehensive examination and may be consulted in judging the presentation when it bears upon their areas of expertise.

To be eligible to take the Comprehensive Examination, the student must have a cumulative average of 3.00 or greater on appropriate graduate coursework at The University of Iowa. Appropriate graduate coursework includes review courses (Section II.B.), graded seminar presentations (Section III.F.), courses that satisfy the advanced course requirement (Section III.A.), and additional courses in chemistry or related disciplines that are judged appropriate by the student’s GAC. Graduate Chemistry Orientation (CHEM:5091, formerly 4:191), Ethics in Chemical Sciences (CHEM:5092, formerly 4;192), Research in Chemistry (CHEM:7999, formerly 4:290) and Research Seminar (CHEM:6990, formerly 4:291) shall be graded on an S/U basis and therefore are not included in the computation of the cumulative average.

The general comprehensive examination requirements set by the Graduate College must be completed by the end of the fourth semester in residence, unless written consent is received from the GAC and is approved by the Departmental Graduate Review Committee (DGRC). A student who fails to meet this requirement may be dropped from the PhD program. A student on academic probation is not eligible to take the comprehensive exam. Students entering with a Master's degree and those exempted from review courses are strongly encouraged to take the comprehensive examination during the second or third semester in residence.

The comprehensive examination is a two-part oral examination. The first part consists of an oral defense of the student's research problem and progress, and will be based upon a written Research Report submitted by the student. The second part consists of an oral defense of an original Research Proposal submitted by the student. The Research Report and the Research Proposal must be submitted (together) prior to five weeks before the last day of classes in the semester during which the examination is to be taken (or, for a spring semester examination, by the last Friday prior to Spring Break, whichever is earlier). It is strongly recommended that the examination be held at the earliest possible date in the semester to facilitate scheduling.

If the GAC approves both the Research Report and the Research Proposal, the oral examination may be scheduled. The student should then complete a Formal Plan of Study and a Request to the Graduate College for the PhD Comprehensive Examination. At the examination, the student will be asked to present a short (20 minute) summary of their research project. During or following this presentation, the committee will ask questions designed to probe the student's understanding of the research topic and important background material, the experimental methods and techniques which are important in the particular area, and the goals and significance of the research. The committee next will examine the candidate's understanding of areas related to the Research Proposal. The student will be asked to give a short (30 minute) presentation of the Research Proposal. The committee will ask questions designed to probe the quality and the student's understanding of the proposal. Typically, however, this discussion will evolve into a wide-ranging examination of the student's general competency in the chemical sciences.

Seminar requirements

Each student is expected to give a minimum of two acceptable seminars. One seminar must cover the student's research. The other may also deal with the student's research, or can be an extensive literature report. The student may register for the appropriate divisional seminar course and receive letter grade credit during those semesters in which the seminars are presented. The final PhD defense cannot be used to meet this requirement.

The research conference/three-month seminar

At least three months before the anticipated final defense, the PhD candidate must meet with their graduate academic committee. If scheduling permits, the research work can be reported as a research seminar during a regularly scheduled divisional seminar, with a subsequent committee meeting for questions and advice.

Final defense of the PhD dissertation

The Dean of the Graduate College will make a public announcement of a candidate’s final defense three weeks prior to the exam date. This final oral examination is open to the public. Dissertation copies must be made available to all members of the examining committee not later than two weeks before the examination date.

“Opposing Motor Memories in the Direct and Indirect Pathways of the Basal Ganglia”

Abstract:  Loss of dopamine neurons causes motor deterioration in Parkinson’s disease patients. We have previously reported that in addition to acute motor impairment, the impaired motor behavior is encoded into long-term memory in an experience-dependent and task-specific manner, a phenomenon we refer to as aberrant inhibitory motor learning. Although normal motor learning and aberrant inhibitory learning oppose each other and this is manifested in apparent motor performance, in the present study, we found that normal motor memory acquired prior to aberrant inhibitory learning remains preserved in the brain, suggesting the existence of independent storage. To investigate the neuronal circuits underlying these two opposing memories, we took advantage of the RNA-binding protein YTHDF1, an m6A RNA methylation reader involved in the regulation of protein synthesis and learning/memory. Conditional deletion of Ythdf1 in either D1 or D2 receptor-expressing neurons revealed that normal motor memory is stored in the D1 (direct) pathway of the basal ganglia, while inhibitory memory is stored in the D2 (indirect) pathway. Furthermore, fiber photometry recordings of GCaMP signals from striatal D1 (dSPN) and D2 (iSPN) receptor-expressing neurons support the preservation of normal memory in the direct pathway after aberrant inhibitory learning, with activities of dSPN predictive of motor performance. Finally, a computational model based on activities of motor cortical neurons, dSPN and iSPN neurons, and their interactions through the basal ganglia loops supports the above observations. These findings have important implications for novel approaches in treating Parkinson’s disease by reactivating preserved normal memory, and in treating hyperkinetic movement disorders such as chorea or tics by erasing aberrant motor memories.
