Welcome to the Department of Biological Sciences, in the Columbian College of Arts and Sciences. Faculty in our department teach and pursue research on a broad range of biological topics, from the molecular level to the organismal and ecosystem levels and on organisms covering a broad spectrum of taxonomic diversity.

The Biological Sciences major is one of the most popular in the Columbian College, especially among students preparing for medical, dental, and veterinary programs and graduate programs in biology, zoology and botany. Our faculty and graduate students actively engaged in research here on campus and in field sites around the world, and often collaborate with researchers at one of the many research institutes in the Washington, D.C., area.
