Joseph Ladapo, M.D., Ph.D.

A Short Biography:

Joseph A. Ladapo, MD, PhD, is a physician and health policy researcher whose primary research interests include assessing the cost-effectiveness of diagnostic technologies and reducing the population burden of cardiovascular disease. He is Associate Professor at the David Geffen School of Medicine and cares for hospitalized patients. Previously, he served as a faculty member in the Department of Population Health at NYU School of Medicine and as a Staff Fellow at the Food and Drug Administration.

Dr. Ladapo’s research program, funded by the NHLBI, NIMHD, and the Robert Wood Johnson Foundation, focuses on (1) patient-centered approaches to improving the health of individuals evaluated for coronary artery disease, and (2) behavioral economic interventions to promote sustainable cardiovascular health, including among adults with HIV. He also leads the health economic and quality of life evaluation of multiple NIH-funded randomized trials focused on cardiovascular disease and tobacco cessation. His national honors include the Daniel Ford Award for health services and outcomes research, and he was also a regular columnist for the Harvard Focus during medical school and residency, where he discussed his experiences on the medical wards and perspectives on health policy issues.

Dr. Ladapo graduated from Wake Forest University and received his MD from Harvard Medical School and his PhD in Health Policy from Harvard Graduate School of Arts and Sciences. He completed his clinical training in internal medicine at the Beth Israel Deaconess Medical Center.
