The Doctor of Philosophy degree is offered by the Department. Original research, performed under the direction of a thesis advisor, plays a major role in this degree. The thesis research helps the student to develop research skills, critical judgment, originality, and independence. It is through participation in such research that the graduate student makes the transition from the role of student to that of professional colleague.

Students join research groups and choose thesis topics during the first semester of residence, after discussion with faculty members. Most students begin research at the beginning of their second semester at MIT.

The Doctor of Philosophy degree in Chemistry requires completion of a program of advanced study, two semesters of teaching experience, completion of cumulative written examinations and a general oral examination, and completion and oral defense of a thesis on original research.
