I have three major areas of research: groups, the self, and violence. My research on groups examines processes involved in intergroup conflict and intragroup harmony. Relevant questions addressed by this line of research are "Why are relations between groups more competitive and abrasive than relations between individuals?" and "Why and under what circumstances do persons enact behaviors and thoughts that are beneficial to other members of their own social group?"
My research on the self explores the interplay between the individual-self (i.e., self as unique independent social agent) and the collective-self (i.e., self as interchangeable group member). My recent efforts have been addressing the question "Given that both the individual and collective selves are valid and important forms of self-definition, which form of self-definition is more primary?"
My research on violence examines processes that contribute to physical attacks against close-relationship members and violence directed toward numerous persons (e.g., school shootings at Columbine High School). My recent efforts have been examining whether a group-dynamic is involved in attacks directed toward numerous persons. In particular, are the persons who are victimized in episodes of mass violence the intended target or is the intended target the social group to which the victimized persons belong?
