I study politics under conditions of violence, state weakness, and democratic backsliding. My research combines rigorous fieldwork, experiments, and causal inference to inform better policies and stronger democracies.

My research examines the political economy of violence, organized crime, policing, and democratic governance in Latin America. I study how criminal violence, weak and corrupt institutions, and punitive security policies reshape state–society relations, fuel human rights abuses, and undermine democratic institutions.
Building on my work on democratic backsliding, I also examine the tradeoffs citizens face when deciding whether to defend or abandon democracy in contexts of insecurity, polarization, and state weakness. More broadly, my research seeks to understand how institutions and public policies can reduce violence, strengthen the rule of law, and promote democratic resilience.
My teaching takes place in the classroom, the lab, and the field. In the lab I bring together graduate and undergraduate students who take part in sponsored research projects, learning to tackle challenging real-world problems — and I take students to do fieldwork in Guatemala, Brazil, and Mexico.
