Dr. Andrew Stewart’s research focuses on understanding and developing novel means for inducing the replication and regeneration of insulin-producing pancreatic beta cells. As Chief of the Division of Endocrinology and Metabolism at the University of Pittsburgh School of Medicine, Dr. Stewart and his research team were the first to demonstrate that adult human beta cells could be induced to replicate at substantial rates. Three long-time colleagues from that group are joining him: Donald K. Scott, PhD; Adolfo García-Ocaña, PhD; and Rupangi Chhaya Vasavada, PhD, as Professors in the Division of Endocrinology, Diabetes and Bone Disease, and as members of the Institute. Dr. Stewart, who has also been named Professor of Medicine (Endocrinology, Diabetes & Bone Diseases) will oversee the continued expansion of the Institute through the recruitment of additional researchers.

Dr. Stewart has devoted more than 30 years to patient care and scientific research, and received numerous honors, including the prestigious Aurbach award of The Endocrine Society, and also served as Program Chair for the American Diabetes Association Annual Scientific Sessions in 2010 and 2012.  He has published more than 230 clinical and scientific papers in journals including the Proceedings of the National Academy of Sciences, The New England Journal of Medicine, and Science.  He received his bachelor's degree from Trinity College in Hartford, Connecticut, and his MD from Columbia University, College of Physicians and Surgeons, in New York.  He served as a fellow in Endocrinology and Metabolism and faculty member at Yale University School of Medicine in Connecticut, and later as Chief of the Division of Endocrinology at the University of Pittsburgh.  Dr. Stewart currently has strong funding support from the National Institutes of Health, the Juvenile Diabetes Research Foundation, and other agencies.
