Yimin (Amy) Ge

I am a postdoctoral fellow at the Johns Hopkins Bloomberg School of Public Health Department of Health Policy and Management, the Center for Mental Health and Addiction Policy (CMAP), and the Hopkins Business of Health Initiative (HBHI). I received my Ph.D. in Public Policy and Management from the Sol Price School of Public Policy at the University of Southern California. 

My research examines how policies and health care systems shape access to and quality of care, with a particular focus on mental health and substance use disorder (SUD) treatment. I approach these questions as a health economist and policy researcher, using advanced quantitative methods and large-scale administrative data to evaluate the impacts of federal and state reforms as well as market interventions. I also employ qualitative methods that bring contextual depth and real-world perspectives to my analyses. Collectively, my research aims to inform evidence-based policymaking by identifying how structural and policy environments influence treatment access and outcomes, particularly among socioeconomically disadvantaged populations.
