Research Interests

I lead an interdisciplinary research program that is specifically aimed at the goal of improving health outcomes for patients with infectious diseases including HIV and HCV, substance use disorders, and other vulnerable populations. My research, which uses clinical epidemiology, health economics, simulation modeling, and cost-effectiveness, informs clinical-decision making and health policy to answer clinically- and policy-relevant questions. I am engaged in research using these innovative methods to help understand the impact of and improve upon policies that affect people who use drugs infected with or at high risk for infections. My research is currently been funded by NIDA in the form of both a K01 and a DP2 award as well as multiple grants for which I am a Co-Investigator. I have also received NIAID, the Providence/Boston Center for AIDS Research (CFAR), the BU-CTSI, and the MGH Executive Committee on Research Fund for Medical Discovery. I currently serve as Director of the Health Economics and Modeling Core for the Massachusetts HEALing Communities Study, an NIH-funded grant to significantly reduce overdose. I am the previous recipient of the Charles A. King Trust Research Award, and the prestigious AAMC Herbert W. Nickens Faculty Fellowship Award, which recognizes a junior faculty member who demonstrates leadership potential in addressing inequity in health care. I have published my work and editorials in leading journals such as NEJM, Lancet Public Health, JAMA Internal Medicine, AJPH, Addiction, Clinical Infectious Diseases, and Annals of Internal Medicine. My work has been widely cited in the media, including the Boston Globe, U.S. News and World Report, and NPR.
