STEP Educational Program

The Science, Technology, and Environmental Policy (STEP) Program encourages Master's and PhD students to acquire a sophisticated understanding of key issues at the intersection of science, technology, and policy. STEP blends scientific knowledge and methods with social science and practitioner perspectives in ways that yield practical solutions to the major scientific, environmental, and technological challenges facing the world today.

Several certificate and fellowship opportunities comprise the STEP Program, which is centered in the Princeton School of Public and International Affairs. STEP provides a larger umbrella for Princeton graduate students generally interested in science policy, and has deep connections to the Center for Policy Research on Energy and the Environment (C-PREE), the High Meadows Environmental Initiative (HMEI), and the Center for Information Technology Policy (CITP). Students work closely with distinguished STEP faculty, who come from diverse academic backgrounds, including natural science, engineering, and social science departments, to integrate their science and policy interests.
