Derek LeRoith, M.D., Ph.D is an endocrinologist and Professor of Medicine and the current Chief of the Hilda and J. Lester Gabrilove, M.D. Division of Endocrinology, Diabetes and Bone Disease and Director of the Metabolism Institute of the Mount Sinai Medical Center in New York City. He is an international expert in insulin-like growth factor-1 (IGF-1).
LeRoith was the first to demonstrate the link between insulin-like growth factor-1 (IGF-1) and cancer and is the current recipient of an NCI grant to study the relationship between cancer and type 2 diabetes. He is the author of more than 500 publications and an editor of more than 20 textbooks on endocrinology.
LeRoith was born in 1945 in South Africa. He earned both his M.B. Ch.B. and his Ph.D. from the University of Cape Town. In 1974, he became a fellow of the College of Physicians of South Africa, and, in 1975, he became a member of the Royal College of Physicians of the United Kingdom. His post-doctoral training included a residency in pediatrics at the Kaplan Medical Center in Rehovot, Israel, an endocrine research fellowship at the University of Cape Town, and a residency in medicine and geriatrics at Middlesex Hospital in London.
In Israel, LeRoith held a lectureship in medicine and endocrinology at the Ben-Gurion University of the Negev. In 1979, he joined the United States' National Institutes of Health and eventually became the Chief of its Diabetes Branch of the Institute of Diabetes and Digestive and Kidney Diseases.
LeRoith is a board member for the Council for the Advancement of Diabetes Research and Education and the Endocrine Fellows Foundation. He serves on the scientific advisory board of Medingo, Ltd. and is a past member of the national board of directors for the American Diabetes Association. He has served on the editorial board of 18 journals, including Endocrinology, Experimental Cell Research, the Journal of Clinical Endocrinology and Metabolism, the Journal of Clinical Investigation, the American Journal of Physiology and the Journal of Biological Chemistry. He served on the review committees of the United States Department of Veterans Affairs and the American Diabetes Association.
