Dr. Marc A. Zimmerman's research focuses on adolescent health and resiliency, and empowerment theory. His work focuses on violence and firearm injury prevention. His research on adolescent health examines how positive factors in adolescents' lives help them overcome risks they face for violent and aggressive behavior. Although most of his work includes community prevention program development and evaluation with community partners, he also conducts survey research, longitudinal studies, and more in-depth qualitative approaches. Dr. Zimmerman's application of empowerment theory includes a violence prevention program called Youth Empowerment Solutions (yes.sph.umich.edu). The research includes both longitudinal interview studies and community intervention research. Dr. Zimmerman is the Editor of Youth and Society.
