Organismic and Evolutionary Biology is one of the programs in the Harvard Integrated Life Sciences, which facilitates collaboration and cross-disciplinary research. Visit HILS for additional application instructions.

The Department of Organismic and Evolutionary Biology (OEB) is committed to training scientists who pursue a greater understanding of the evolution of the earth’s life processes. More than ever before, human activity places species and ecosystems at risk, and the need for research addressing environmental issues of global proportion has never been more urgent. The department’s faculty and students examine significant biological processes that span a continuum from single cells to entire ecosystems, conducting field and laboratory studies that are key to understanding the evolution of organisms, how biodiversity is generated and maintained, how organisms work, and how organisms interact with their environment.

The department's programs, many of which are interdisciplinary or linked to research in other departments, constitute a frontier of scientific vision in organismic and evolutionary biology. Modern research facilities, combined with the natural history collections and libraries of the Harvard University Herbaria and the Museum of Comparative Zoology, provide unique opportunities for meeting the challenges inherent in this pursuit. Other resources include the Concord Field Station of the MCZ, the Harvard Forest, and the Arnold Arboretum, and graduate students benefit from OEB’s connections in the life and physical sciences, including the Department of Molecular and Cellular Biology, human evolutionary biology, systems biology, the Center for Brain Science, the Department of Psychology, the Broad Institute, the Departments of Earth and Planetary Sciences and Physics, as well as the Harvard John A. Paulson School of Engineering and Applied Sciences.

Admissions Requirements

Potential applicants are encouraged to identify and contact faculty with whom they might work if admitted to OEB’s graduate program by reviewing the department’s current research areas. Interviews with prospective faculty advisors are strongly recommended.
