I am an Assistant Professor of Sociology at the University of California, Los Angeles.
My research lies at the intersection of sociology, history, political science, and, increasingly, social psychology. 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 the 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 the causes and consequences of violence.
My book, Sacred Treason: Why Catholic Bishops Defected From Vichy to Support Jews During the Holocaust, 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 or is forthcoming 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.
