Stefanos Zenios is the Charles A. Holloway Professor of Operations, Information and Technology at the Graduate School of Business, Stanford University and Director, Program in Health Care Innovation. His research is concerned with how health care delivery systems use technology to prolong life and improve its quality for patients with complex and expensive medical needs. He is especially interested in the impact the decisions of providers and payers have on the innovators. Some of the issues he examines include: medical technology adoption through shared decision making between physicians and patients; financial incentives for the adoption and initiation of complex treatments; differences in the utilization of medical technology and outcomes between for-profit and nonprofit health care providers; evidence-based decision making and its effect on equitable utilization of medical technology; the value of life implied by existing medical practice and its implications; and early-stage business models in medical technology. Professor Zenios has explored these questions in the context of end-stage organ failure and particularly kidney failure. His research was supported by grants from the NIH, by the prestigious CAREER award from NSF, and by Stanford Hospital and Clinic. Zenios received a BA and MA in Mathematics from Cambridge University, England, and a PhD in Operations Research from MIT.
