Dr. Sara B. Johnson is an associate professor of pediatrics at the Johns Hopkins University School of Medicine with a joint appointment in the Department of Population, Family and Reproductive Health in the Bloomberg School of Public Health. She serves as the Co-Director of the Rales Center for the Integration of Health and Education and the Director of the General Academic Pediatrics Fellowship Program.
Dr. Johnson's research is focused on understanding and reducing disparities in child health and achievement. She studies how adverse experiences (e.g., poverty, trauma, stress) shape the biology of child health and development and ways to mitigate these effects. She is particularly interested in the development and malleability of behavioral and physiological self-regulation from the fetal period to adolescence.
Dr. Johnson' s other research interests include adolescent health, particularly neurodevelopment in adolescence and its implications for adolescent health policy, and social influences on brain and behavioral development.

Research & Publications
Dr. Johnson’s research interest is in understanding how social experiences (e.g., poverty, family relationships, neighborhood characteristics and life events) shape the biology of child development. Specifically, she is interested in the development and plasticity of behavioral and physiological self-regulation. She has examined the role of early life stress in shaping self-regulatory development from the fetal period to age five. Other research interests include neurodevelopment in adolescence and its implications for adolescent health policy, social influences on neurodevelopmental trajectories, and adolescent injury prevention.
