The major is a part of the Department of Biology, an academic unit within the College of Science and Mathematics.

The biology major offers a liberal arts and sciences program of study that gives students the foundation for entry into a broad spectrum of professional opportunities. An important feature of the program is its strong emphasis on providing students with independent undergraduate research opportunities. The core curriculum includes classes that emphasize laboratory experience and process in science. This laboratory emphasis continues in upper division course work. Biology, as a science, is very diverse and is reflected in the research interests of the biology faculty. Refer to the biology departmental website for more information about faculty research interests.
