Melissa Tracy PhD, MPH

Social determinants of mental health and substance use, particularly after exposure to violence and other traumatic events. I am also interested in the application of novel methods to population health problems, including the use of agent-based modeling to compare potential policies and interventions for reducing health disparities.
