The Department of Ecology and Evolutionary Biology at Yale University is home to broad, interdisciplinary and highly collaborative research with particular expertise in population, community, ecosystem, and macroecology; in evolutionary genetics, developmental evolution, behavioral evolution, and evolutionary medicine; and in phylogenetics, systematics, and biodiversity.  We are committed to producing world-class scientists, educators and professionals through undergraduate and graduate education.

About Us

The Department of Ecology and Evolutionary Biology was created in 1997 and currently comprises 14 primary and 14 affiliated faculty members, approximately 40 graduate students, 50 postdoctorals, lecturers and research scientists, and 100 undergraduates with an EEB concentration.  Our offices and laboratories are spread across the historic Osborn Memorial Laboratories (OML), the Environmental Science Center (ESC) and Building 31 on Yale’s West Campus. 

The mission of the Department of Ecology and Evolutionary Biology at Yale University is to achieve the highest possible quality of research, undergraduate, and graduate education in the fields of ecology, evolution, and organismal biology.

We discover, create, synthesize, and disseminate knowledge about the earth’s biodiversity, its ecological interactions, and its evolutionary history.  We pursue integrative, interdisciplinary, and global research on phenomena that range from molecules to ecosystems.

We prepare Yale College undergraduate majors for careers in biology and medicine and educate other Yale College students in ecology, evolution, and biodiversity.

We seek to attract the most capable, promising, and diverse graduate students and postdoctoral appointees from the nation and the world and to prepare them for positions of leadership in research, education, and society.
