Biology students, faculty, and staff work together to better understand the nature and significance of living systems.

The Department of Biology is an interactive community of undergraduates, faculty, and staff who work together to better understand the nature and significance of living systems

We share a common commitment both to biology as a scientific discipline and to the importance of biology in broader social and cultural contexts.

The Biology curriculum is designed to introduce students to unifying concepts and broad issues in biology, and to provide the opportunity for in-depth inquiry into topics of particular interest through coursework and independent research.
