Why Study Environmental Science and Policy at Mason?


First in the country to offer a PhD program that explicitly blends Environmental Science and Public Policy.


Over 100,000 middle school students reached since 2009 through the PEREC Field Interpreter environmental stewardship program.


Steady year-on-year increase in enrollment in the B.S. in Environmental Science degree program over the last 5 years.

Our strategic approach to academic and research excellence

Every student pursues their own passion and conducts research in that area to contribute to the health of our environment. Undergraduates can choose from 6 concentrations, drawn from our three areas of expertise: water and watersheds, One Health, and conservation.


Potomac Environmental Research and Education Center (PEREC)

We have a multi-investigator research and education center on the tidal Potomac River - the Potomac Science Center. About half of the ESP core faculty is housed here.


Mason Students in the Field

At Mason, lots of learning takes place outside the classroom. Our students have research opportunities taking them from sea level to five stories above it! And with key partnerships like Smithsonian-Mason School of Conservation, you can be hanging out with endangered red pandas while earning class credit. The temperature may be hot, but doing research doesn’t get any cooler than this!
