Each graduate student must write a doctoral dissertation that includes significant original research in Computer Science. The student must successfully defend his or her thesis in a public forum before an Examination Committee and any other interested parties. The Examination Committee will decide the format for the defense. Typically, the student gives a 45-50 minute talk about her work followed by a public question period and then a private question period. All faculty are invited to stay for the private part of the exam.
Each student must present his work at a public dissertation defense. Please see here for the rules that apply to all oral examinations.
