Mary E. Schwab-Stone, M.D., is a child psychiatrist with training in epidemiology. Her research has been guided by an interest in the relationship between the social environment and psychological adjustment in childhood, with a particular emphasis on children growing up in situations of social and economic disadvantage. In recent years this interest has become focused specifically on school-based programs for the prevention of psychological difficulties and the promotion of healthy development in children in urban settings. She has collaborated with the New Haven Public Schools as a program consultant, and heads the Yale-based team responsible for evaluation of their social development and prevention programming. She has served as a clinical consultant to the Special Education Program in the New Haven Schools for a number of years. After graduating from Harvard University, she earned her M.D. at Dartmouth Medical School. She did residency training in adult and child psychiatry at the Massachusetts Mental Health Center in Boston. After clinical training she was on the staff at McLean Hospital in Belmont, Massachusetts, and did part-time psychiatric practice. In 1984, she decided to pursue more actively a longstanding interest in child psychiatric research by undertaking a research training fellowship in child psychiatry and epidemiology at Columbia College of Physicians and Surgeons. She moved to New Haven in 1986 where she is currently Harris Associate Professor of Child Psychiatry at the Yale Child Study Center. She served as Acting Director of the Collaborative for the Advancement of Social and Emotional Learning (CASEL) until October 1996 and continues to serve on the CASEL Leadership Team.
