Which public policies reduce violence in the world's most dangerous cities? How can policing institutions be reformed to increase citizen trust? How should the state seek to re-establish control after civil war? How do ex-combatants and ordinary citizens perceive peacebuilding efforts? What are the consequences of commonly-used drug policies?
To answer these questions—in Colombia, Mexico, Brazil, and Central America—I work with international organizations, national and local governments, and use a combination of experimental and quasi-experimental quantitative methods.
