Dr. Johnson’s research is broadly focused on how early life environments may lead to biologic and cognitive changes that affect health in adolescence and young adulthood. She is particularly interested in how the social environment may affect neurodevelopment and the development of self-regulation.  Trained in public health, Dr. Johnson is a former Robert Wood Johnson Health and Society Scholar at the University of California, San Francisco and UC Berkeley. Her current work examines the links between early life social environments, the development of the stress response system, and reactivity and self-regulation in adolescence. Her other research interests include the role of adolescent neurodevelopment in risk of injury and violence, and adolescent injury prevention policy.  She received her masters and doctoral degrees in public health from the Johns Hopkins Bloomberg School of Public Health.
