Graduate Program Options

Members of the Department of Organismic and Evolutionary Biology share a primary commitment to train scientists pursuing a greater understanding of the evolution of the earth's life processes. More than ever before, human activity places species and ecosystems at risk.

The need for research addressing environmental issues of global proportion has never been more urgent. Together, faculty and students examine significant biological processes which span a continuum from single cells to entire ecosystems.

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.

The OEB Graduate Program

Application & Admissions

OEB's graduate program is part of Harvard's Integrated Life Sciences Program (HILS). A description of recommended academic preparation, requirements, and admission and financial aid procedures and deadlines are available online through the Graduate School of Arts and Sciences (GSAS) Web sites.

Potential applicants are encouraged to identify and contact faculty with whom they might work if admitted to OEB's graduate program. We list OEB's current research areas, and faculty working in those areas on this website.

Applications to OEB's graduate program can only be submitted through the GSAS online application is the recommended format.

If you have further questions about OEB Graduate Program, please don't hesitate to contact the Senior Academic Programs Administrator for OEB, Alexander Hernandez-Siegel, at or (617) 384-9271.


The Molecules, Cells and Organisms PhD Program (MCO)

Application & Admissions

Several faculty members from OEB are also mentors in the MCO PhD Program, a multi-departmental pre-doctoral training program administered through the Department of Molecular and Cellular Biology. For a listing of the OEB faculty members who are members of the MCO PhD Program, please click here.

To apply to the MCO PhD program, please do so via the Molecular and Cellular Biology Department. There, you can indicate which track of the program you are interested in. If you have further questions about MCO, please don't hesitate to contact the Graduate Program Coordinator for the MCO PhD Program, Patricia Perez, at or (617) 496-8262.
