Biology, Ph.D.

Doctoral studies in biology at ¶¶Òõpro emphasize intensive research training under the direction of a member of the graduate faculty. Once biology Ph.D. students at SLU successfully complete the required coursework and the written and oral qualifying examinations, they are expected to design and conduct an original research project and to work independently.

Students will be required to present their work at local or national professional meetings and may also be expected to seek external funding to support the research project. Ideally, a student's research will result in publication in peer-reviewed scientific journals.Ìý

Curriculum Overview

SLU's Ph.D. in Biology requires a minimum of 36 post-baccalaureate credits, with at least 24 credits of coursework and 12 credits of dissertation research.

Careers

Past biology Ph.D. students at SLU have gone on to careers as research scientists, teachers, university faculty and in various capacities at pharmaceutical companies and government agencies.

Admission Requirements

Suggested courses include biology (a minimum of eighteen [18] upper-division credits); chemistry (a minimum of eight [8] upper-division credits including two semesters of organic chemistry or one semester of organic chemistry and the other of biochemistry); physics (two semesters); mathematics (through a course in calculus). A formal minor is not permitted.

For students interested in ecology, evolution or systematics, additional coursework in some of the following areas is also recommended: genetics, general ecology, evolution, introductory statistics, general botany, and a taxonomically oriented course. For students interested in cell or molecular biology, additional coursework in some of the following areas is recommended: genetics, biochemistry, cell biology, physiology, molecular biology, microbiology or immunology.

Previous laboratory and research experience preferred.

Non-Course Requirements

New Ph.D. degree students who enter the program with a B.S. or B.A. degree may take the written preliminary exam the first or second spring semester they are in the program. New Ph.D. students who enter the program with a master’s degree are required to take the written preliminary exam the first spring semester they are at SLU.

All doctoral students must pass written and oral exams to advance to candidacy; these are typically attempted at the end of the second and third semesters, respectively. All doctoral students must also complete one year of teaching. This can be accomplished by serving as a graduate teaching assistant, by completing two semesters of a practicum in a teaching course, or by other teaching experience approved by the student's committee and the department chair.

Continuation Standards

Students must maintain a cumulative grade point average (GPA) of 3.00 in all graduate/professional courses.

Roadmaps are recommended semester-by-semester plans of study for programs and assume full-time enrollmentÌýunless otherwise noted. Ìý

Courses and milestones designated as critical (marked with !) must be completed in the semester listed to ensure a timely graduation. Transfer credit may change the roadmap.

This roadmap should not be used in the place of regular academic advising appointments. All students are encouraged to meet with their advisor/mentor each semester. Requirements, course availability and sequencing are subject to change.
