  • Transcript records should reveal a strong background in biological sciences; preferably including biochemistry, biology, calculus, chemistry, genetics, immunology, microbiology, physics and physiology.

Graduate Assistantships and Fellowships:

Admittance of students into the program is dependent on the availability of a Major Professor and a Laboratory willing to accept and provide financial support. Assistantships are limited and are funded through research grants of the major professor, making it necessary to match applicants with faculty before acceptance into our graduate program. 

Most assistantship and fellowship decisions are made by mid-April. To have the best chance of qualifying for financial support, your application (including transcripts and letters of recommendation) must be receivedby February 1 for admission to the Fall Semester.
