The candidate should work out a thesis proposal in consultation with his or her dissertation chair. (See Selection of a Dissertation Chair.) The proposal shall be formally presented at an open meeting of the thesis committee for approval within approximately four months of passing the oral examination. Immediately following completion of the proposal presentation, the student's dissertation chair (in consultation with the rest of the student's dissertation committee) will provide the student with a written evaluation of the student's proposal, providing specific suggestions on how the student can improve his or her dissertation research.
