My research is framed by an intergroup developmental approach to study risk and resilience processes for youth in settings of protracted conflict. My work has implications for youth outcomes, such as aggression, prosocial behaviours and social identity, as well as broader psychosocial processes, such as shared education and intergroup relations, which may fuel or constrain conflict. Toward this end, I study how and why violence affects behaviours and attitudes related to conflict transformation, primarily during adolescence.
