Professor Camille Pecastaing is director of the Behavioral Sociology Project at the Paul H. Nitze School of Advanced International Studies. He currently works on the cognitive and emotive foundations of xenophobic social attitudes and ethnoreligious violence, using the Muslim world and its European and Asian peripheries as a case study. His areas of expertise include evolutionary and social psychology and the historical sociology of the southern flank of the Eurasian continent, with Islam as the origin of a coordinate system that ranges from the Mediterranean world to East Asia. His work has appeared in Foreign Affairs and Foreign Policy, among other journals.
