Welcome to my webpage. I am a Professor of Government at Georgetown University, where I am also core faculty of the M.A. in Conflict Resolution, and a faculty affiliate of Gui2de, the BMW Center for German and European Studies, and the Center for Latin American Studies (CLAS).

My research and teaching are at the intersection of comparative politics and international relations. I obtained my Ph.D. from Yale University in 2010. I have been an Assistant Professor of Political Science at Duke University (2012-2017), a Niehaus Visiting Associate Research Scholar at the School of Public and International Affairs at Princeton University (2015-16), and Chair of Excellence at Universidad Carlos III de Madrid (2017).

My first book, Rivalry and Revenge: the Politics of Violence during Civil War, was published in 2017 by Cambridge University Press (Cambridge Studies in Comparative Politics). The book, which can be purchased at Cambridge University Press or Bookshop (among other sites), was a runner-up for the Conflict Research Society Book of the Year Award (2018).  The Catalan press ICIP/Edicions Bellaterra published the Spanish translation of the book in their series Colección Paz y Seguridad.

My research has also been published (or is forthcoming) in leading peer-reviewed journals such as the American Journal of Political Science, American Political Science Review, Journal of Politics,  Proceedings of the National Academy of Sciences,  among several other outlets.

I received the ISA's prestigious Emerging Scholar Award in International Security Studies. Other awards I received include the Luebbert Award for the Best Article in Comparative Politics from the American Political Science Association (with Stathis Kalyvas); outstanding Paper award from ISA's Ethnicity, Nationalism, and Migration section in 2018 (with Gerard Torrats-Espinosa) and in 2020 (with Spencer Dorsey and Juan Tellez). I have also received (with Abel Escribà and Lesley-Ann Daniels) an Honorable Mention in the Best Paper Award of the APSA Conflict Processes Section, and (with Elsa Voytas and Valeria Palanza) an Honorable Mention in the Outstanding Paper Award of the APSA Democracy & Autocracy Section. In 2025, I also received a best paper award from the Catalan  Institut d'Estudis de l'Autogovern (with Lesley-Ann Daniels and Alexander Kuo).

As Principal Investigator (PI), I have received grants from the Harry Frank Guggenheim Foundation, the Folke Bernadotte Academy, the World Bank, UNU-WIDER, and the Catalan Institute of Peace (ICIP). I have also received collaborative grants from the ESRC (United Kingdom), the Spanish Ministry of Science, and the Research Council of Norway, among others. I am affiliated with HiCN, and a member of the International Academic Council of the Institut Barcelona Estudis Internacionals (IBEI).

I am chairing the Carolina de Miguel Moyer Young Scholar Award committee. The Council of European Studies (CES) instituted the award in 2021 to honor Dr. Carolina de Miguel Moyer, a beloved friend who left us too early in the summer of 2020.

Since June 2024, I serve as Associate Editor of the American Political Science Review.
