Instructions on presenting your thesis or project defense: First contact your committee members and negotiate a time which is good for you and them. When you have decided on a time, ask the Math Office to book a room. Also, send them a message containing your name, the title of your thesis or project, the name of your advisor, an abstract describing your thesis orproject, and the date and time of your defense. The Math Office will send out an announcement a few days before the defense.
