My research focuses on the psychological impact of group-based victimization on people’s self-concept and on relations with members of other groups (in particular other disadvantaged or victimized groups). More specifically, I am interested in the social psychological processes and conditions that give rise to constructive, rather than to destructive consequences of victimization. I study these questions among various ethnic, religious and national (minority) groups in the U.S., Europe, India, and in East Africa. Another focus of my research lies in psychological processes that occur during and in the aftermath of genocide. I have a strong interest in the use of multiple methods, and in the integration of theories across subdisciplines (such as social psychology and peace psychology; and social and clinical psychology) as well as between disciplines (such as history and psychology).
