Carl Ronald Kahn (born January 14, 1944) is an American physician and scientist, best known for his work with insulin receptors and insulin resistance in diabetes and obesity. He is the Chief Academic Officer at Joslin Diabetes Center, the Mary K. Iacocca Professor of Medicine at Harvard Medical School[1] and a member of the National Academy of Sciences since 1999.[2]
Kahn became the president and director of Joslin in 2000 and held this position until 2007. In 2012, he was appointed Joslin's first Chief Academic Officer.[3]
Outside of Joslin, Kahn also held various leadership roles. In 1998 he was appointed chair of the Congressionally-mandated Diabetes Research Working Group (DRWG).[4] This group developed a strategic plan which served as the roadmap for growth of the diabetes research for the United States over the following 10 years. Dr. Kahn also served as chair of Class IV (Biomedical Sciences) of the National Academy of Sciences from 2007 to 2010.
Kahn is an investigator in insulin signal transduction and mechanisms of altered signaling in diabetes. The main discoveries to come from his lab include the insulin receptorkinase, its two primary substrates and the molecular components of the insulin signaling network. Kahn's lab was also the first to define alterations in the signaling network in insulin resistant states, such as type 2 diabetes.[5] More recent discoveries from his lab encompass defining alterations in the signaling network in type 2 diabetes, including the important role of insulin action in unexpected tissues such as brain, both in physiologic regulation and potentially in development of Alzheimer's disease. His lab at Joslin has also made contributions to the understanding of obesity by showing that fat cells, called adipocytes, have different developmental origins and cellular functions that lead to risk of metabolic disease.
Kahn's work with adult humans has demonstrated that they have active brown fat that is central to redefining its role in metabolic regulation and protection from obesity.[6]
