About

I am a Postdoctoral Research Associate at the Brown School of Public Health, in the Department of Health Services, Policy & Practice. My research uses health economics, public finance, and industrial organization frameworks to examine why healthcare markets fail patients and what policies can do about it. I focus on addiction treatment access, the cost and quality of available care, and how Medicaid policy, telehealth rules, and provider entry/exit reshape the delivery system at scale.

My research has been published in JAMA, Health Affairs, JAMA Network Open, and Annals of Internal Medicine; recognized among the annual Best and Highest Impact selections by Annals of Internal Medicine, AcademyHealth, and the American Society of Addiction Medicine; and covered by NPR, The New York Times, The Washington Post, CNN, and Reuters. It has been cited in policy and clinical guidance from US federal agencies, professional societies, and state governments — including HHS proposed rulemaking on the DATA Waiver Program (42 CFR 8). I have presented findings to the US Senate, the Federal Trade Commission, the Department of Justice, the Joint Commission, the World Health Organization, and the United Nations Office on Drugs and Crime. I have served as principal investigator on an NIH dissertation award (NIDA R36) and a RAND Corporation pilot, with additional research and training support from the National Institute on Drug Abuse, the Agency for Healthcare Research and Quality, and Yale's Institution for Social and Policy Studies.

I joined Brown after completing my PhD in Health Policy & Management (Economics track) at Yale and my MPH at the Harvard T.H. Chan School of Public Health.
