Dr. Grych’s primary research interests focus on understanding factors that promote resilience in children and adolescents, the potential for bystander intervention to reduce sexual and physical violence, and the study and measurement of aggression in family and romantic relationships.

Research Lab: Resilience and Relationships Lab


Ph.D., U of Illinois at Urbana-Champaign, 1991

Research Interests

My students and I currently are conducting research in two areas. First, the development of resilience in youths exposed to violence and other types of adversity. We are investigating intrapersonal, relational, and community factors that promote healthy functioning from preschool through adolescence. We are particularly interested in families and schools as contexts for development, and collaborate with local organizations and institutions in this work. Second, we have longstanding interests in the origins, consequences, and assessment of aggression in close relationships. At present, we primarily are focused on understanding factors that facilitate and interfere with responsive bystander behavior in high risk situations and on enhancing efforts to reduce sexual and physical assaults on college campuses.  We are collaborating with researchers at several universities across the US in this work.
