Hillary Samples, PhD, MHS

Core Faculty


Hillary Samples works with large health care databases and national data for studies examining patterns of drug use and behavioral health treatment, the association with health outcomes, and the role of policy in improving access to evidence-based care and reducing the burden of mental health and substance use problems in the U.S. Her research broadly aims to advance knowledge of effective practices and policies to improve behavioral health and well-being at a population level and increase equity for disadvantaged groups. Her work has been supported by the National Institute on Drug Abuse and published in high-impact journals, such as JAMA Open, Journal of General Internal Medicine, Epidemiology, and Health Affairs.

Dr. Samples joined Rutgers in 2020 as Assistant Professor of Health Systems and Policy at the School of Public Health and is a core member of PETS. She completed a post-doctoral fellowship in Substance Abuse Epidemiology at the Columbia University Mailman School of Public Health after earning her PhD in Health Services Research and Policy, her MHS in Population Mental Health, and a Certificate of Bioethics and Public Health Policy from the Johns Hopkins Bloomberg School of Public Health.
