Our Team!

Our research team is dedicated to generating new knowledge that can inform interventions and policies aimed at improving the lives of adolescents. We use a variety of rigorous and innovative research methods, including surveys, interviews, and magnetic resonance imaging, to investigate topics such as social and emotional development, risky behavior, protective factors for mental health, and effective interventions for mental health problems.
