The Princeton Environmental Institute (PEI) coordinates environmental education and research on the Princeton campus, manages multidisciplinary research projects, administers the PEI Science, Technology and Environmental Policy (PEI/STEP) fellowship program and organizes courses and seminars on topics of general environmental interest. PEI fosters interdisciplinary collaboration among faculty and students and helps forge links among the many departments in the science and humanities involved in the study of the environment. Students are based in a home department, but participate in research and teaching in environmental science, technology and policy with faculty members from across the campus.

Areas of particular strength in which students may wish to concentrate their graduate education include: global change, biogeochemical cycles, molecular geochemistry, biodiversity and conservation, environmental science and policy, and environmental history.

Graduate programs with substantial environmental content can be found in the following departments and programs: Atmospheric and Oceanic Sciences, Chemical Engineering, Chemistry, Civil and Environmental Engineering, Ecology and Evolutionary Biology, Geosciences, Mechanical and Aerospace Engineering, and the Science, Technology and Environmental Policy Program (STEP) of the Woodrow Wilson School, among others. Please contact these programs directly for further information.
