Be a hero; Chair a Doctoral Exam!

Among the most critical elements of any doctoral exam, from the perspective of those who coordinate these complexities, is the search for a strong Chair. Yet this search serves as a perennial challenge to the Doctoral Examinations team. We consider ourselves very lucky indeed if we issue fewer than 10 invitations before confirming 1 chair for an upcoming exam. It is not at all unusual in some disciplines to invite 30 or more chairs before some gracious faculty member agrees to help us out.

If you would like to contribute your time and wisdom to UBC’s doctoral exams:

  • Please have a look at the list of upcoming exams below and if one interests you, please send us an email to
  • Or send us an email detailing the areas that interest you and days/times that you might be generally available and we'll contact you as new exams are scheduled. Again, send an email to


Please bear in mind that the chair cannot be affiliated with the candidate’s graduate program, or a member of the supervisor's department..
