Irl B. Hirsch, MD, is a professor of medicine and holds the Diabetes Treatment and Teaching Chair at the University of Washington School of Medicine in Seattle. Dr. Hirsch went to medical school at the University of Missouri in Columbia, Missouri, trained in internal medicine at the University of Miami in Miami, Florida and Mt Sinai Hospital in Miami Beach, Florida, and completed a research fellowship at Washington University in St Louis.

Dr. Hirsch has been interested in new technologies for the treatment of diabetes, particularly those involved in the use of insulin therapy. He has also been interested in the mechanisms of how insulin co-modulates inflammation with glucose and how this results in improvements in outcomes, particularly of hospitalized patients. The management of hyperglycemia in the hospital has been an interest of Dr. Hirsch for over 25 years. He has been involved in numerous major clinical research trials, including the DCCT, ACCORD, STAR-1, JDRF Sensor Trial, SEARCH, ORIGIN, ADAG, and many more particularly involved with insulin therapy. He is interested in the use of computers in diabetes data management, and how pattern recognition can be used to improve diabetes control, in addition to how glycemic variability noted on glucose meter downloads may be an independent risk for microvascular complications. These ideas have led to successful funding of FLAT-SUGAR (FLuctuAtion reducTion with inSUlin and Glp-1 Added togetheR), completed in 2013.

He also has a very active clinical practice of which 80% of patients have type 1 diabetes. He has authored over 140 papers including a review of insulin in the New England Journal of Medicine, over 50 editorials, three commentaries in the Journal of the American Medical Association, numerous book chapters, and four books for both patients and physicians. He is the past editor-in-chief of DOC News and Clinical Diabetes. He is the former chair the Professional Practice Committee for the American Diabetes Association and served as a member of the Endocrine Section of the American Board of Internal Medicine.
