My research focuses on addressing the drivers of health inequities (including mental health, substance use, and cancer) in marginalized groups, including people living with HIV, those at risk for HIV, and those involved in the criminal justice system. I am the co-founder of the Community Health Justice Lab (http://www.chjl.org), where members and trainees address inequity in health prevention strategies and social determinants of health through community research with and for medically underserved populations.
