The Graduate Field of Ecology and Evolutionary Biology encompasses the study of organic diversity, including its origins, dynamics, maintenance and consequences. Our faculty and graduate students pursue topics across a broad span of interconnected fields, including ecosystem biology, community and population biology, organismal biology, molecular ecology, population genetics, 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.
