I am a postdoctoral fellow at the Watson Institute for International and Public Affairs at Brown University. My research focuses on the sources of cooperation in interstate rivalries. I also study the causes and consequences of nuclear proliferation, U.S. defense policy, and the politics of South Asia. Previously, I was a predoctoral fellow at the Belfer Center for Science and International Affairs at Harvard University, a Stanton Nuclear Security Predoctoral Fellow at the RAND Corporation in Washington, D.C., and a Council on Foreign Relations International Affairs Fellow in India. I also served as country director for South Asian affairs in the Office of the Secretary of Defense (2006–2009), a research associate at the Naval Postgraduate School in Monterey, Calif. (2003–2005), and a research assistant at the Henry L. Stimson Center in Washington, D.C. (2001–2003). I received a PhD in Political Science from MIT, an MA in National Security Affairs from the Naval Postgraduate School, and a BA in History and International Studies from Wichita State University.
