I manage the Civic Integrity Research team at Facebook. Before joining Facebook, I was a senior research analyst at Langer Research Associates, a leading survey research and analysis firm based in New York, and I served as an Assistant Professor in the Political Studies Division at the Centro de Investigación y Docencia Económicas (CIDE) in Mexico City, where I remain an Affiliated Professor.  I received my PhD in political science from the University of Notre Dame.

This is the home of my academic research, which has broadly focused on public opinion, political behavior and survey research methods in the Americas. My dissertation explains why mass commitment to democracy varies across citizens and countries, particularly in the new democracies of Latin America. A paper based on this research received the American Political Science Association's 2014 Franklin L. Burdette/ Pi Sigma Alpha Award, which recognizes the best paper presented at the 2013 APSA Annual Meeting. Beyond this research interest in mass attitudes to democracy, my research also includes a large-scale study of clientelism and electoral intimidation in Latin America and projects employing multilevel regression with poststratification (MRP) to forecast public opinion and electoral behavior in the United States.  My research has appeared or is forthcoming in the American Journal of Political Science, Political Behavior, Public Opinion Quarterly, Comparative Political Studies, and Latin American Research Review.
