Our Department is dedicated to research, education, and practice on public health issues rooted in human behavior and social conditions—from smoking and substance use to diabetes and HIV and more. We develop and evaluate individually targeted interventions, work with communities to address social factors that affect health, and improve  public policy and other structural factors to improve the health of millions at a time.
