Ana Arjona is Assistant Professor of Political Science at Northwestern University. She obtained her PhD from Yale University. Her academic interests focus on violent conflict, the foundations of political order, state building, local governance, and the links between crime and politics. She is also interested in the philosophy of social science. Her current research projects investigate the causes and consequences of institutional change and individual agency in contexts of violence. She is the author of Rebelocracy: Social Order in the Colombian Civil War (in press, Cambridge University Press) and co-editor of Rebel Governance in Civil War (Cambridge University Press, 2015, with Nelson Kasfir and Zachariah Mampilly).
