Dr. Johnson’s research focuses on understanding how early life experiences (e.g., poverty, trauma, life events) shape the biology of child and adolescent health and development. Currently, she is investigating biological and social mechanisms in the intergenerational transmission of health disparities. Other research interests include brain development adolescence and its implications for adolescent health policy, social influences on neurodevelopmental trajectories, and adolescent injury and violence prevention.

Dr. Johnson serves as the Co-Director of the Rales Center for the Integration of Health and Education in the Johns Hopkins Children's Center. The Center is focused on testing new models of school-based health programming to reduce health and educational disparities. She also directs the Johns Hopkins General Pediatrics Fellowship Program.
