About the Program

The Department of Biology offers a graduate program in biological sciences leading to the Doctor of Philosophy degree. The curricula and research programs are designed to help students achieve success in their degree programs and pursue positions of leadership in their respective fields of research.

The intellectual life of the department relies heavily on the participation, creativity, and the energy of graduate students; therefore the department expects students to be vigorously involved in courses, seminars, journal clubs, research, informal discussions, and departmental functions.

Degree Requirements

The Doctor of Philosophy in Biological Sciences is conferred in recognition of breadth of scholarship and scientific attainment plus demonstrated ability to complete original research.

The following general requirements must be satisfied in order to complete the PhD program in Biological Sciences:

  • 90.0 (post-bac) or 45.0 (post-MS) credit hours total
  • Establishing a plan of study
  • 7 core courses
  • Additional courses dependent on advisor or committee recommendations
  • Candidacy exam/approval of dissertation proposal
  • Dissertation/thesis
  • Defense of dissertation/thesis
  • A graduate research seminar presentation once a year for students in their third year and beyond.

Thesis Advisor/Plan of Study

For students admitted without an identified thesis advisor, the thesis advisor must be selected by the end of spring term in the first year. All students are asked to submit a plan of study by the end of the first year winter quarter. It is anticipated that the graduate coursework will be completed during the first two years or less. Students should check with the department for a list of available electives.
