The doctoral program in Materials Science consists of taking a series of preparatory classes, followed by an oral candidacy exam, a written thesis, and a final oral thesis defense. The goals of this program are to develop competence in a chosen field of specialization; to develop tools with which to assess problems outside the student's field of specialization; to develop sufficient strength in the physical sciences for self-education beyond formal training; and to cultivate the motivation and foresight to become a productive and influential leader. As such, the graduate program in Materials Science is designed to be a doctoral program and students are only admitted into the doctoral program. There is no separate master’s program in Materials Science, however, a degree of Master of Science in Materials Science can be awarded upon request by students after the fulfillment of course requirements. The Ph.D. degree in Materials Science is focused on research. Study and research programs for the Ph.D. degree are individually planned to fit the interests and background of the student. A comprehensive research project resulting in an original contribution to the field documented by a dissertation is required.
