His book project, “Save a Neighbor, Shoot a Stranger,” seeks to understand the role of cross-group social ties in both rescue and betrayal during social unrest, genocide, and civil war. His work has been supported by the Harry Frank Guggenheim Foundation, the U.S. Department of Defense, and the Post-Conflict Research Center in Sarajevo.
