The Civil Conflict and Democratic Erosion Policy Lab aims to produce rigorous empirical evidence to better understand and counter threats to peace and democracy both in the US and around the world. The Lab combines research with teaching and policy engagement, and directly involves both graduate and undergraduate students in the production of new knowledge. Current projects include a randomized controlled trial and survey experiment to evaluate the impact of military involvement in domestic policing operations in Colombia;  surveys and administrative data collection to study the causes and consequences of violence against environmental activists in the Brazilian Amazon; and a series of randomized controlled trials to test mechanisms for reducing partisan polarization in the US.
