I am an Assistant Professor of Sociology at the University of California, Los Angeles. 

My research lies at the intersection of sociology, history, and political science. I am fascinated by how individuals make decisions about violence: whether to organize, support, and participate in violence; how, when, and why they choose to defect; and what happens once violence is done. Accordingly, my research and teaching interests span political sociology and violence, how social categories and identity processes bear on violence and mobilization, comparative-historical sociology, and questions about the relationship between social perception, culture in action, and moral judgment. I use a range of comparative-historical, qualitative, and experimental methods to develop falsifiable theories about violence.

My book, Sacred Treason: Race, Religion, and The Holocaust in France, is currently under contract with Harvard University Press. Another book, the second Handbook of The Sociology of Morality, is under contract with Springer (co-authored with Shai Dromi and Steve Hitlin). My research has appeared in Political Power & Social Theory; Qualitative Sociology; Sociological Theory; Socius; European Journal of Sociology, and several other journals and edited volumes. I have also published numerous op-Eds and interviews in The Washington Post; New Yorker; LA Times; NY Times, and elsewhere. Prior to my time at UCLA, I worked in various capacities for USAID, United Nations CTED, Montreal Institute for Genocide Studies, and Facing History & Ourselves.
