A large portion of my research is dedicated to evaluating applied health programs, and I am particularly interested in the healthcare safety net and disadvantaged populations. As a researcher in New Mexico, there are many important and complicated health issues confronting our populations, including crime, substance abuse, and health disparities. To address these issues I have worked with researchers from many other disciplines including: law, psychology, medicine, engineering, and criminal justice. I have evaluated a number of programs in a number of different areas including drug courts, interventions for risky sexual behavior, telemedicine programs and care management for high-cost medically complex patients. Also, I am increasingly interested in empirical methods used to understand incentives and/or behavior when market data is not available or when traditional identification strategies do not work (e.g., surveys, changes in property values and/or voting behavior). I am particularly interested in the secondary impacts and unintended consequences of policies that are intended to mitigate risky health behavior.

Erika Martin, PhD, MPH
Erika Martin is an associate professor in the Department of Public Administration and Policy at SUNY-Albany. Dr. Martin uses mixed methods to evaluate the allocation of scarce public health resources, adoption and impact of public health policies, and ways to improve the sustainability and impact of open health data platforms. Her work in HIV policy includes evaluating: federal Ryan White funding formulas, interstate variation in HIV drug formularies, the budget impact of expanded HIV screening, repealing the ban on federal funding for syringe exchange, how the Affordable Care Act will affect HIV care, the impact of New York’s HIV testing law and Ending the Epidemic policy strategies, and the evolution of New York’s policy response to opioid overdose. In addition to her HIV policy research, she studies how public health agencies can release open data in a way that is more usable and fit for public health research. She has considerable experience working with government clients to translate evidence-based research into practice.
She received her B.A. from Brown University, her M.P.H. in Epidemiology from the University of Michigan, and her Ph.D. in Health Policy and Administration from Yale University.
