Graduate Degrees in Ecology & Evolutionary Biology

Ecology & Evolutionary Biology

The ecology and evolutionary biology (EBIO) graduate program provides advanced training in a wide variety of biological disciplines ranging from biogeochemistry to community ecology to evolutionary genetics. The goal of the EBIO graduate program is to produce scientists, educators and citizens who are equipped with skills to build careers that advance knowledge about life on Earth. 

Our department offers programs leading to the Master of Arts and Doctor of Philosophy in a wide variety of biological disciplines. Graduates of the EBIO program are well positioned to pursue a range of careers that include academia, science education, wildlife biology, conservation biology, resource management, environmental consulting and environmental law.

Graduate student support is available in the form of fellowships, part-time instructorships, teaching assistantships, research assistantships and research grants.  

Modern laboratory facilities for graduate study are located in the Ramaley Biology building.

The department has strong ties with the CU Museum of Natural History, the Institute of Arctic and Alpine Research (INSTAAR), the Institute for Behavioral Genetics (IBG), the Cooperative Institute for Research in Environmental Sciences (CIRES), the Environmental Studies Program (ENVS) and the departments of Integrative Physiology; Geology; Geography; Anthropology; and Molecular, Cellular and Developmental Biology.
