Dr. Erin Trish is an Assistant Research Professor at the USC Price School of Public Policy. She completed a postdoctoral fellowship at the USC Schaeffer Center for Health Policy and Economics and the Fielding School of Public Health at the University of California, Los Angeles. She was one of only seven recipients to be awarded the 2014 USC Provost’s Postdoctoral Scholar Research Grant. She graduated from the Johns Hopkins Bloomberg School of Public health in 2013 with a doctorate in Health Policy and Economics. She also holds a B.S. in Biomedical Engineering from Johns Hopkins University and worked as a research assistant in a stem cell research lab at Harvard University prior to starting graduate school.  

Her research focuses on private health insurance markets in the US, including how the Affordable Care Act may affect how these markets function. Her dissertation research focused on the offsetting effects of the level of competition among insurers on health insurance premiums and on how insurance market regulations affect employers’ decisions about the health benefits they offer. During her postdoctoral fellowship she researched trends in employer-sponsored insurance, particularly among smaller employers, including evaluating the impact of insurance rating regulations on firms’ decisions to offer and/or self-insure their health benefits.  Additionally, she has worked on several other research projects related to the ACA including simulations of the population expected to obtain coverage through the exchanges as well as the risk adjustment programs included in the law.

Her current research is focused on the impact of the Affordable Care Act on insurer and provider markets, analyzing market forces that impact insurer-provider negotiations over payment rates, and healthcare spending.
