About

As Penn’s hub for research on population health, the health care system, and health policy, LDI supports, connects, engages, and amplifies interdisciplinary research among experts from all of Penn’s schools, the University of Pennsylvania Health System, and the Children’s Hospital of Philadelphia.


LDI is headquartered in the Colonial Penn Center Building at the center of Penn's campus.

The Leonard Davis Institute of Health Economics

With a gift from Leonard and Sophie Davis, the University of Pennsylvania established the Leonard Davis Institute of Health Economics (LDI) in 1967, two years after Congress enacted Medicare. It was created to fill fundamental gaps in the evidence base that could inform policies critical to the financing and management of the nation's increasingly costly and complex health care system. Today, LDI is considered one of the world’s leading university institutes dedicated to data-driven, policy-focused research that improves our nation’s health and health care.

As Penn’s hub for research on population health, the health care system, and health policy, LDI supports, connects, engages, and amplifies interdisciplinary research among experts from all of Penn’s schools, the University of Pennsylvania Health System, and the Children’s Hospital of Philadelphia. LDI brings together more than 300 Senior Fellows whose work fits broadly within LDI’s four priority areas that highlight some of the most pressing challenges facing our nation’s health system today: (1) care for vulnerable populations; (2) coverage and access to health care; (3) improving care for older adults; and (4) the opioid epidemic.

LDI trains the next generation of health services and health policy researchers through a resource-rich environment and innovative educational programs at the undergraduate, masters, doctoral, and postdoctoral levels. LDI’s role as an active convener at Penn is augmented by a dynamic research and policy seminar series, conferences, and a growing number of research partnerships with academic and service organizations regionally and nationally.
