Our Research
Our research examines how health policies, reforms, and systems shape health care access and affordability, quality, and population health outcomes across the United States. We use state-of-the-science methods to produce rigorous, actionable evidence — holding policy to the same evidentiary standards we demand of clinical medicine. From the design of national value-based payment programs under the Affordable Care Act, to the structure of Medicare and Medicaid, to safety-net programs and policies making prescription drugs and health care more affordable (such as the Inflation Reduction Act), our work touches the policies that shape health care for millions of Americans.
Our section is led by Dr. Rishi Wadhera, a nationally recognized cardiologist, health policy researcher, and outcomes scientist. Our findings are frequently published in leading medical journals, including the New England Journal of Medicine, JAMA, and The Lancet, and have been cited in Congressional reports, Senate testimonies, MedPAC reports, American College of Cardiology/American Heart Association clinical practice guidelines, and by senior leaders at the Centers for Medicare and Medicaid Services. Our work has directly influenced federal health policy — research from our group demonstrating the unintended consequences of pay-for-performance policies, for example, has helped reshape how these initiatives are designed, implemented, and evaluated on a national scale.
Our research is also regularly covered in the New York Times, NPR, NBC News, and STAT News. Alongside this research mission, we are deeply committed to training the next generation of physician-scientists and health policy researchers.
Rishi K. Wadhera, MD, MPP, MPhil
Rishi K. Wadhera, MD, MPP, MPhil is a cardiologist, health policy researcher, and Associate Professor at Harvard Medical School and the Harvard T.H. Chan School of Public Health. He serves as Associate Director of the Smith Center for Outcomes Research, where he founded the Section of Health Policy Research, building it into a large, multidisciplinary team of 15 full-time clinician-investigators, research staff, and postdoctoral fellows. He is an elected member of the American Society of Clinical Investigation.
Dr. Wadhera's research — informed by his frontline experience as a practicing cardiologist — applies the evidentiary rigor of clinical medicine to the evaluation of health policy, asking not just what policies intend, but how they actually affect patients. He is the principal investigator of three NIH R01 grants and a recipient of the American Heart Association Established Investigator Award, and has authored more than 280 peer-reviewed publications in leading medical and health policy journals. He has advised senior leaders at the US Department of Health and Human Services, the Centers for Medicare and Medicaid Services, and Congressional committees, and is widely cited as a health policy expert by the New York Times, NPR, the Boston Globe, and NBC News. He serves as Associate Editor at the Journal of the American College of Cardiology and on standing advisory panels for the Institute for Clinical and Economic Review and the National Committee for Quality Assurance. A defining feature of his work is mentorship and faculty development. He has trained more than 40 junior investigators who have collectively first-authored more than 110 publications and secured competitive career development awards, with many advancing to independent academic careers across the country.
