Study in this program emphasizes environmental and evolutionary biology. Students enrolled in the program are expected to concentrate their dissertation work in an area of active faculty research. Admission to the program is highly competitive and is dependent on both student credentials and the ability of our department to provide stipend support. This degree is most suitable for applicants pursuing careers in research or higher education.
