Graduate Defences


Final oral examinations may be conducted online (via MS Teams) or in-person. Please review the appropriate defence notice (below).

Tips for Remote Thesis Defences and Oral Qualifying Exams   While observers are very welcome, they must follow all instructions given by the exam chair, including the tips listed here.  Please join the meeting via the link, found in the email announcement to the department.  Keep your microphone muted unless invited to speak by exam chair.  Join with your name or a static profile picture to cut down on visual distractions.  Do not send the student any messages in the chat during the defence.  If appropriate, the exam chair will invite questions from the audience after the oral presentation is done.  Leave the meeting, as appropriate, when instructed by the exam chair.  Thank you for your cooperation.
