Charles E Phelps, PhD, University Professor and Provost Emeritus of the University of Rochester (Rochester, NY USA), health economist, has published major theoretical and applied research in health economics and particularly in cost-effectiveness analysis since beginning his career at the RAND Corporation, including a founding role in the RAND Health Insurance Experiment. During his time on the active faculty of the University of Rochester (1984 – 2010), he served for five years as chair of the (currently named) Department of Public Health Sciences, and then (for 13 years) as Provost of the University of Rochester. His more recent work has focused on expanding cost-effectiveness analysis using multi-criteria decision analysis (MCDA) models, voting theory (to improve use of MCDA models in group settings), and systems approaches to evaluating health care. His textbook, Health Economics, is in its sixth edition (2017) and (with Stephen T. Parente) published in 2017 a new book entitled “The Economics of US Health Care Policy.” He was elected to the Institute of Medicine (now the National Academy of Medicine) in 1991. Professor Phelps served as a member of the ISPOR Task Force on Value in Health in 2016-2017.
