Dr. Green's research focuses on drug abuse and addiction. Specifically, the areas in which she is most interested and to which she has contributed include the intersecting worlds of HIV infection and drug abuse, non-medical use of prescription drugs, corrections health, drug policy, and opioid overdose prevention and intervention. By consequence, this work addresses issues of health disparities, gender, and place effects on health. She studies drug abuse and addiction within a chronic disease framework, incorporating methods from epidemiology, psychology, statistics, and geography. Her dissertation examined longitudinal patterns of drug abuse and their effects on medication adherence, disease progression, and mortality among a cohort of aging US veterans with and without HIV infection, an effort supported by an individual Kirschstein National Research Service Award Pre-Doctoral Fellowship. She earned a MSc in Epidemiology and Biostatistics from McGill University and a PhD in Epidemiology from Yale University where she was a Center for Interdisciplinary Research on AIDS pre-doctoral fellow.
