Biology courses 60-72 credit hours to include:

Topical seminar BIOL 792 - TOPICS IN BIOLOGY (C) or NSCI 792 - TOPICS (C) (minimum of four different 1+ credit hour topic courses required)
Graduate Seminar BIOL 890 - Ph.D. SEMINAR IN BIOLOGY 4-5 credit hours (no more than 5 credit hours will count toward program of study)

Supporting courses subject to approval of student’s dissertation advisory committee 0-12 credit hours

Note:

NSCI 792/other topics courses will fulfill the four course topics requirement. Courses taken under a different prefix will be considered supporting coursework and will not count toward the required 60 credit hours of BIOL courses.
50% of the program of study must be at the 700-level or above.
Up to 18 credit hours from a previous master’s degree can be applied towards Biology or supporting courses.

Dissertation Research

The area of concentration for this degree may be selected from the various biological specialties (e.g., ecology, cell biology, developmental biology, molecular biology, evolution, neuroscience, physiology). Completion of the degree requires a demonstrated ability to conduct original and independent research. Each doctoral student is required to take a comprehensive oral examination before the beginning of the third year, after completion of most of the coursework. Candidates for the Ph.D. degree present a departmental seminar and take a final oral examination that addresses the dissertation as well as evaluates the student’s knowledge of broader aspects of biology. See http://www.usd.edu/arts-and-sciences/biology/graduate.cfm for a description of the advisory committee, the annual progress report, the comprehensive oral examination, the dissertation proposal, and recommended timetable for completion of the degree.
