Dissertation Committee: Roles, Functions, and How to Choose

The path to a dissertation is filled with choices that determine the quality of your experience as a student as well as the future strength of your professional network. 

Choosing your dissertation committee is one of the most important decisions–and one of the most fraught–that you’ll make as a graduate student. With the stakes being so high, many doctoral students worry about making a misstep and getting it wrong. 

Fear not! Putting together your dissertation committee becomes easier once you know the right questions to ask: of potential committee members, of your dissertation chair, and of yourself. While forming your dissertation committee can be challenging, striking the right balance will lead to a richly rewarding academic experience that will pay dividends throughout your career. Do your homework, and you’ll be just fine.

What Does a Dissertation Committee Do?

The basic function of your dissertation committee, which typically consists of five members, is to guide you through the process of proposing, writing, and revising your dissertation. 

Dissertation committee members serve in a mentoring capacity, offering constructive feedback on your writing and research, as well as guiding your revision efforts. They are also the gatekeepers of the ivory tower, and the ultimate judges of whether or not your dissertation passes muster. 

The dissertation committee is usually formed once your academic coursework is completed. It is not uncommon in the humanities and social sciences for dissertation committee members to also write and evaluate qualifying exams, and of course serve as faculty. By the time you begin working on your dissertation, you may know the faculty members who will serve on your dissertation committee quite well. 

Who Serves on Your Dissertation Committee? 

To a degree, who serves on your dissertation committee is up to you. Dissertation committees usually consist mostly of faculty members from the doctoral student’s home department, though this can vary due to the rise of interdisciplinary programs. 

Some universities also allow an outside expert–a former professor or academic mentor from another university–to serve on your committee. It’s advisable to choose faculty members who know you and who are familiar with your work. 

While it’s a good idea to have a mix of faculty members, it’s also important to be mindful about the roles they can play. For instance, I always advise graduate students working in quantitative fields to have a statistician on their committee. When there’s big data to crunch, it never hurts to have a stats expert in your corner. You’ll also want at least one faculty member–besides your chair–whose research is in the same relative area as yours, or adjacent to it. 

How to Choose Dissertation Committee Members

Think Carefully. It’s tempting to approach a faculty member who is a superstar in their field (if not, necessarily, in yours) to lend a little extra sparkle to your own academic credentials. Or perhaps the kindly professor you can always count on for an easy A. Or even the faculty member you’d like to be friends with after graduate school. Right? 

Not so fast. Here are some things to keep in mind when building your dissertation committee dream team: 

• Avoid Superstars. Though the prospect of having your department’s most eminent name on your committee sounds exciting, their star power comes with a price. Between guest lectures, books, keynotes, and conference travel, their time is not their own, and it won’t be yours, either. Choose dissertation committee members who have time for you. 
• Choose faculty members you know, like, and can learn from. It’s not a bad idea to approach a professor whose coursework challenged you. One of the professors who served on my committee was such an exacting grader that my term papers for her courses were accepted for publication without revision (academia’s most coveted mythical creature). 
• Keep your eyes on the future. Members of your dissertation committee can be your mentors, co-authors, and research collaborators throughout your career. Choose them wisely. 

Forming Your Dissertation Committee

Reaching out to potential dissertation committee members and formally asking them to serve on your dissertation committee can be a surprisingly taxing process. It takes some planning, and you’ll want to put some thought into it before making the big ask. While being asked to serve on a dissertation committee won’t come as a surprise to most faculty–they know the drill–these are some considerations to know going in:

• Talk to your advisor before approaching anyone to be on your committee. Remember, your advisor knows their colleagues in a way that you don’t, and is also aware of departmental politics, potential personality conflicts, and which faculty members are a good fit on a dissertation committee. Trust your advisor’s judgement. 
• Know what you’re asking. Serving on a dissertation committee is a big time commitment for any faculty member. If they say yes to being on your committee, it means they are invested in you and your research, and they want to play a role in your future. It doesn’t hurt to send a thank-you note. 
• Don’t sweat it if they say no. It does not reflect on you as a student or a scholar. A good faculty member is aware of their limitations, and they probably just don’t have the time or bandwidth to take on another big commitment. Thank them and move on. 

Expectations

Once your dissertation committee is formed, it’s time to get down to business. As a faculty member, I love serving on dissertation committees because doing so gives me the chance to work with grad students one on one as they journey into new frontiers and carve a place for themselves in academia. It is a deep, rich learning experience, and it’s thrilling to watch students transform into scholars. 

Even though researching and writing a dissertation is the most challenging work you’ll ever do, recognize this time for the opportunity it truly represents. In your dissertation committee, you have a panel of experts all to yourself, and they’re eager to help you knock your dissertation out of the park. This is the experience of a lifetime; take advantage of your dissertation committee’s time and talent, and channel that energy and goodwill into your development as a scholar.
