Key Consultants


Roger Unger is Professor of Internal Medicine and holds the Touchstone/West Distinguished Chair in Diabetes Research at University of Texas Southwestern. His lab is best known for its studies of islet physiology, including the elucidation of the roles of insulin and glucagon in regulating normal blood glucose homeostasis and in the pathogenesis of diabetes and the establishment of glucagon as a hormone. Recently his lab introduced the concept of lipotoxicity, the process by which overaccumulation of lipids in obesity in nonadipose tissues leads to diabetes and to metabolic syndrome. His group has demonstrated the role of leptin action in preventing fat-induced islet failure and metabolic syndrome. Dr. Unger received the Banting Medal of the American Diabetes Association, the Rumbaugh Award of the Juvenile Diabetes Association, the Claude Bernard Medal of the European Association for the Study of Diabetes, and the Koch Award of the Endocrine Society. He is a member of the National Academy of Sciences and of the American Academy of Arts and Sciences and was Director of the Touchstone Center for Diabetes Research from 1986 until 2007. Dr. Unger earned his M.D. from Columbia University.

Robert R. Henry, M.D., is Professor of Medicine in the Division of Endocrinology & Metabolism at University of California San Diego (UCSD). He is also chief of the Endocrinology, Metabolism & Diabetes section and the Center for Metabolic Research at the Veterans Affairs Medical Center in San Diego. Dr. Henry received his M.D. from the University of Manitoba Medical School in Canada. He was a former president of the American Diabetes Association Medicine and Science. Dr. Henry’s many memberships and accolades include: American Association of Clinical Endocrinology, European Association for the Study of Diabetes, the Distinguished Clinical Scientist Award from the American Diabetes Association, the Mary Jane Kugal Award of the Juvenile Diabetes Research Foundation International, Frontiers in Science Award from American Association of Clinical Endocrinology, and the Banting Medal for Public Service from the American Diabetes Association, to name a few.
