Thomas M. Maddox, MD MSc


Director, Health Systems Innovation Lab

Dr. Maddox is the inaugural Director of the Health Systems Innovation Laboratory (HSIL) at BJC HealthCare and the Washington University School of Medicine in St. Louis. He is also a practicing cardiologist, a Professor of Medicine (Cardiology) at the Washington University School of Medicine, and a health services researcher.


HSIL identifies and implements innovations in data, analytics, technology, and care delivery to improve the health of patients and their communities. Cross-disciplinary in nature, HSIL facilitates health delivery innovations by bringing together clinicians, patients, informaticians, researchers, public health experts, and private industry. As promising innovations are developed, HSIL helps implement, evaluate, and spread them across BJC HealthCare and Washington University care delivery sites, the broader St. Louis community, and beyond. HSIL also serves as a conduit to the national and international healthcare innovation community, facilitating a bidirectional conversation that will accelerate collaborative innovation.

HSIL is specifically focused on developing innovations in four areas: 1) utilizing personalized health data - from genomics to social determinants - to optimally inform care, 2) moving care delivery closer to where patients live, work, and play, 3) harnessing community data for community health, and 4) engaging patients in shared decision-making and longitudinal health behaviors.
