E. Mark Cummings, Ph.D., is Professor and Notre Dame Endowed Chair in Psychology at the University of Notre Dame. Guided by the Emotional Security Theory, his work focuses on processes associated with adaptive and maladaptive family functioning and children’s and adolescents’ development. Dr. Cummings is also interested in relations between family and community contexts and youth development, including pathways to adjustment and well-being in international samples of families exposed to community violence, and relations between political violence, armed conflict, and child development. His current research is also concerned with family- and community-based interventions for families and children. Christine E. Merrilees, Ph.D., is an Assistant Professor in the Psychology Department at the State University of New York at Geneseo. Her research uses developmental and social psychological theory with advanced longitudinal methodsto assess the impacts of conflict and intergroup divide on youth development. Her work has been published in high impact journals in developmental, clinical, and social psychology, and her current research focuses on ethnic identity and contact processes that impact well-being and intergroup attitudes and behavior. Laura K. Taylor, Ph.D., is a Lecturer in the School of Psychology with the Centre of Identity and Intergroup Relations at Queen’s University, Belfast, Northern Ireland. She has published more than two dozen peer-reviewed articles on her research, which uses a developmental intergroup framework to study risk and resilience processes related to the impact of political violence on children, families, and communities. Her more recent work has focused on constructive outcomes and positive youth development. Christina F. Mondi, M.A., is a graduate research fellow of the National Science Foundation and a doctoral student in Developmental Psychopathology and Clinical Science at the University of Minnesota. Her research interests are in socio-emotional processes underlying normal development and the development of psychopathology, and in school- and family-based early childhood interventions.
