My research focuses on the economic consequences of political regimes and on the effects of political institutions on political elite behavior, especially in Latin America, and has appeared in the American Journal of Political Science, the Journal of Politics, and Comparative Political Studies, among others. I am the author of Curbing Bailouts: Bank Crises and Democratic Accountability in Comparative Perspective (2009) and co-author of Latin American Party Systems (2010), The Chain of Representation: Preferences, Institutions, and Policy in Latin America’s Presidential Systems (2020), and Electoral Rules and Representation. Interparty and Intraparty Politics (2025). I was a faculty member at the Instituto Tecnológico Autónomo de México before joining Washington University in 2003, and have held visiting professor appointments at the Institut Barcelona d’Estudis Internacionals in Barcelona and the Hertie School of Governance in Berlin.
