More WashU students major in biology than any other offering in Arts & Sciences. An extraordinary number (more than 75%) of our undergraduates participate in research before graduation.

The department offers seven majors. In addition to the biology major, students interested in a specific subfield may major in one of five optional tracks. The department also offers a major in environmental biology. No matter which major or track you choose, the program in biology provides a thorough education in the history of scientific discovery in biology, the logical and statistical procedures used to formulate and to test biological hypotheses, and technical skills needed for conducting contemporary biological research.
