A minimum of 72 credit hours of instruction is required to complete the MBB Ph.D. You should consult the section "Transfer Credits" in the Graduate Bulletin for rules on how many credit hours may be transferred from another institution. Completion of an M.S. degree is not normally required for admission to the Ph.D. program. You must complete the 21 credit hours of core courses and at least five additional courses from the list of electives.
You must take and pass the written Ph.D. qualifying examination in order to enter into candidacy for the doctorate. In addition, you will be required to pass a comprehensive examination taken prior to performing the major portion of the dissertation research, prior to the sixth semester of study, and at least one year before oral defense of the thesis. This exam partly serves as an oral defense of the thesis proposal.
The final examination for the Ph.D. degree consists of an oral presentation and defense of the dissertation.
The Ph.D. program is tailored to fit your background and goals, and is subject to approval at the time of filing the program of study (Form 401). The program of study must include at least 36 credit hours in formal courses, exclusive of BIOL 691.
