Current Ph.D. Students

Catrina is a second-year Ph.D. student in the Security Studies cluster focusing on irregular warfare, counterterrorism, and quantitative methods. She is also an associate fellow with the Transnational Threats Project at the Center for Strategic and International Studies in Washington, D.C., and a member of the editorial board for the Irregular Warfare Initiative. She was the 2021 counterterrorism fellow at Young Professionals in Foreign Policy. Catrina has previously conducted research at the Migration Policy Institute, the U.S. Treasury Department’s Middle East and North Africa Office, and the Philip Merrill Center for Strategic Studies at Johns Hopkins. She also served for two years in AmeriCorps as a refugee resettlement caseworker in Pittsburgh, Pennsylvania. Catrina holds a B.A. with honors in history, with a concentration in military history, from the University of Chicago and an M.A. with honors in strategic studies and international economics from the Johns Hopkins University School of Advanced International Studies.

Evan is an incoming Ph.D. student in the Science, Technology, and Environmental Policy program. He previously completed his undergraduate degree in chemical engineering from the University of Wisconsin-Madison with a second major in environmental studies, where he engaged in research through the university’s Chemical and Biological Engineering Department at the intersection of modeling and emerging technologies for waste valorization in complex chemical processes and supply chains. He later had the opportunity to complete a policy-focused research internship in Washington, D.C., through the Washington Internships for Students of Engineering (WISE) program. He is driven toward science policy questions surrounding the roles of emerging technologies in broader societal challenges, and is interested in how researchers can use large scale, integrated modeling frameworks to study the economic, environmental, and social implications of the technology’s adoption and its place within existing policy environments. Outside of his primary research interests, Evan is a cellist and also enjoys movies and exploring new places.

Emile is a Ph.D. candidate in Science, Technology, and Environmental Policy (STEP) at Princeton University, advised by Professors Michael Oppenheimer and Filiz Garip. His research interests include climate migration, the societal impacts of climate change, and the development of quantitative methods to address these challenges. Before joining Princeton, Emile was a researcher at Columbia University and the NASA Goddard Institute for Space Studies (GISS), where he worked on improving subseasonal rainfall forecasts using deep learning, investigated the links between climate and food security in Early Modern Europe, and developed statistical models of human migration. He holds bachelor's degrees in economics from Paris-Dauphine/PSL and in mathematics from Sorbonne Université. He also earned a master’s degree in Quantitative Methods in the Social Sciences (QMSS) from Columbia University.

Rifqi is a Ph.D. student in Science, Technology, and Environmental Policy (STEP) at Princeton University. His research explores how energy and economic policy, and the politics surrounding them, can be designed to support creative destruction towards green industrial structure and advance economic development in developing countries. He employs a range of methodological approaches, from energy system modeling to impact evaluation, to produce evidence that informs and strengthens energy and economic policy. Prior to Princeton, Rifqi served in the Government of Indonesia, where he worked on energy, industrial, and investment policy. He also brings hands-on engineering experience in renewable energy deployment and the Internet of Things. Rifqi holds a Bachelor of Science in Electrical Engineering from Institut Teknologi Bandung and a Master of Public Administration from Columbia University.

Sabrina is a third-year Ph.D. student in the Science, Technology, and Environmental Policy (STEP) program focusing on emerging energy technologies and risk perception. Prior to Princeton, she worked as a research assistant to Dr. Robert Rosner and as a liaison to the Bulletin of the Atomic Scientists. Her previous research has included cost models of decarbonizing heavy duty commercial truck transit and the economics of nuclear energy in Europe. She holds a Bachelor of Science in Science, Technology, and International Affairs from Georgetown University and a Master of Public Policy from the University of Chicago.
