My research focuses on processes of social identification and intergroup relations, primarily in the context of large social categories such as nations and ethnic groups. Specifically, my research is at the crossroad of the social psychological areas of norms and morality (e.g., moral disengagement in response to ingroup wrongdoings), intergroup threat (e.g., threat-induced shifting of moral principles such as fairness or loyalty), and social justice (e.g., reparations after ingroup wrongdoings; conflict resolution). Some of the topics I have investigated include: reactions to ingroup-committed torture (supported by the Harry Frank Guggenheim Foundation); American justice appraisals after atrocities committed in Iraq and Afghanistan; and reconciliation strategies in the Israeli-Palestinian conflict. I am currently interested in the search and need for meaning as motives for human "warlikeness" and peacefulness.
