How can the state re-establish control after decades of civil war? What public policies best reduce levels of lethal and non-lethal violence in the world's most violent cities? What role do ordinary citizens play in peacebuilding? Do legacies of violence shape contemporary outcomes and, if so, how?

To answer these questions -- in Colombia, Mexico, El Salvador, Honduras, and Guatemala -- I work with international organizations, national and local governments, and use a combination of primarily experimental and quasi-experimental quantitative methods.
