My research focuses on security topics such as militant group violence and transnational organized crime. You can find my work in outlets such as the Journal of Politics, International Studies Quarterly, Comparative Political Studies, Journal of Conflict Resolution, and Terrorism and Political Violence. Projects I have worked on have been funded by the National Science Foundation, the Mexican Presidency and the U.S. Department of Homeland Security. I am also an affiliated professor at CIDE in Mexico City, where I previously worked for eight years. Before academia, I was enlisted in the U.S. Marine Corps infantry for four years.
