Students with senior standing (or others with consent of the instructor) report on and discuss current biological problems as presented in principle journals, abstracts and reviews. The work of each seminar is usually built upon a single unifying content area.

Continuation of BIO 440. An advanced research project in an advanced student's field of general interest conducted under the supervision of an appropriate staff member, in the form of independent research leading to the solution of a problem.

In-depth study of a specific area in biology, leading to independent research addressing a biological question. Research results will be presented in a professional-style poster at a research symposium. Attendance at biology department seminars is also required.

Terms and hours to be arranged. Graded A-F.
