Experiences & Accomplishments
Dr. Johnson’s research focuses on understanding how chronic stress in early life shapes the biology of child health and development. She is particularly interested in understanding the biological and social mechanisms that help perpetuate health disparities across the life course and across generations and ways to interrupt them. Current projects include an investigation of maternal stress in pregnancy and its impact on child growth via epigenetic mechanisms, and a three-generation study of families in Baltimore focused on understanding pathways to success in the context of early adversity. Dr. Johnson's previous research focused on brain development in adolescence and its implications for adolescent health policy, social influences on neurodevelopment, and adolescent injury and violence prevention.
Dr. Johnson is 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 inequality. She also directs the Johns Hopkins General Pediatrics Fellowship Program.
