Ecology and evolutionary biology is the study of the patterns and processes that structure ecological systems and drive evolutionary change. Understanding the interactions between organisms and their environments is both fascinating and critical for solving environmental problems.

Undergraduate Study

Our undergraduate curriculum is a rich array of innovative lecture, laboratory and field courses that allows students to try out and prepare for diverse career paths in environmental biology, evolutionary biology, or particular kinds of organisms; we invite you to explore our Undergraduate Program page to learn more. Please feel free to also contact our Director of Undergraduate Studies, André Kessler ( if you have further questions about our program, courses, field experiences and research opportunities.

Through coursework, field studies, and faculty-directed research projects, EEB students are exposed to a variety of disciplines and habitats ranging from local freshwaters to terrestrial ecosystems, including agricultural landscapes, to tropical oceans, alpine tundra, deserts and tropical rainforests. For a complete list of courses, follow this link to the Cornell Courses of Study.

Graduate Study

The Graduate Program in Ecology and Evolutionary Biology provides its students with rich opportunities to study biological diversity, including its origins, maintenance and consequences. Our graduate students pursue topics across a broad set of interlinked fields, including ecosystem biology and biogeochemistry, community ecology and population biology, organismal biology, chemical and molecular ecology, population genetics and genomics, speciation and macroevolution.

Prospective graduate students apply to Graduate Fields of Study at Cornell rather than departments. Most Graduate Fields are more inclusive than any one Department. Graduate Fields are, in a sense, virtual, and bring together faculty and students with shared intellectual interests, irrespective of their departmental homes.

Every year in March, EEB along with the Department of Entomology and the School of Integrative Plant Science hosts the annual Diversity Preview Weekend, a two-day event to encourage and assist students from under-represented groups to apply to graduate school a year later (for more information contact
