Successful applicants generally have a minimum undergraduate average of B and high scores on the verbal, quantitative and analytical writing tests of the Graduate Record Examinations (GRE). Applicants must also have earned a B.S. or a B.A. degree and should have at least a minimal background in both physical and biological sciences, including the following: two years of biology, one year each of introductory chemistry, organic chemistry with laboratory, physics, and college level calculus. Although not required, a year of biochemistry is desirable for students interested in cell and molecular biology, and training in statistical analysis is desirable for all students. Special consideration is given to students who have conducted undergraduate research and whose recommendations attest to their skills in the laboratory or field and promise in research. Applicants whose scholarly interests are confluent with those of our Graduate Faculty will also receive priority consideration.
