Dr. Johnson’s research interest is in understanding how social experiences (e.g., poverty, family relationships, neighborhood characteristics, life events) shape the biology of child development. Specifically, she is interested in the development and plasticity of behavioral and physiological self-regulation. She is the recipient of a NIDA Career Development Award to examine 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. Dr. Johnson received her MPH and PhD from the Johns Hopkins Bloomberg School of Public Health.
