Gordon C. Weir, MD is the Diabetes Research and Wellness Foundation Chair at Joslin Diabetes Center, Head of the Section on Islet Transplantation and Cell Biology, and Professor of Medicine at Harvard Medical School. He is a co-author of Endocrinology, 7th Edition.

Dr. Weir completed his medical degree at Harvard Medical School and his residency training at University Hospital in Cleveland. His training in endocrinology was obtained at Massachusetts General Hospital. Before accepting a position at Joslin Diabetes Center in 1984, Dr. Weir was Professor of Medicine at the Medical College of Virginia.

Dr. Weir serves as the Director of the Clinical Islet Transplantation Program at Harvard, a cooperative effort among Joslin, Beth Israel Deaconess Medical Center, Massachusetts General Hospital and Brigham and Women’s Hospital. He is part of the Juvenile Diabetes Research Foundation Center on Immunological Tolerance in Type 1 Diabetes at Harvard Medical School. He also leads the Diabetes Working Group of the Harvard Stem Cell Institute.

Dr. Weir is the recipient of numerous honors and serves and has served on the editorial boards of several prestigious journals, including the American Journal of Physiology, Journal of Clinical Endocrinology and Metabolism, Endocrinology and Transplantation. He also served as editor-in-chief of the journal Diabetes.

Dr. Weir has combined a career of caring for patients with diabetes with an intensive research focus on beta-cell replacement therapy. His research interests include islet-cell transplantation and the function of islets in the normal and diabetic state. A second area of interest has been in developing an alternative source of insulin-producing cells, driven by the shortage of human donor pancreases. In addition, Dr. Weir’s group is investigating the use of genetic manipulation to convert liver cells into beta cells, and developing methods to protect transplanted islet cells from destruction by the immune system.
