Friedman Professor of Surgery and Chief of the Division of Metabolic, Endocrine and Minimally Invasive Surgery at the Mount Sinai Medical Center.  An international authority in the field of minimally invasive endocrine and laparoscopic surgery, Dr Inabnet has pioneered new techniques in minimal access endocrine neck surgery as well as adrenal and pancreatic surgery. In 1998, he performed the first endoscopic thyroid excision in the United States (2nd in the world) with his colleague Dr Michel Gagner. Dr. Inabnet is also a leader in the field of minimally invasive metabolic surgery with a keen interest in disorders of the endocrine system in obese patients, especially type 2 diabetes. Prior to returning to the Department of Surgery at Mount Sinai, Dr. Inabnet served as the Chief of Endocrine Surgery and Co-Director of the Thyroid Center, at the College of Physicians and Surgeons of Columbia University in New York City.

He then fulfilled a fellowship in endocrine surgery at Cochin Hospital in Paris, France where he trained under Professor Yves Chapuis, who was a pioneer in minimally invasive parathyroid, thyroid and adrenal surgery.  Professor Chapuis was a pioneer in developing targeted parathyroid surgery under local anesthesia, having started this approach in the 1980's before surgeons in the United States.  Dr. Inabnet has authored more than 130 peer-reviewed articles and book chapters, as well as 3 textbooks, including the recently released book Endocrine Surgery: Principles and Practice. He lectures throughout the world and was recently inducted into the Society of University Surgeons as well as the French National Academy of Surgery, a rare honor for a non-French surgeon.  Dr. Inabnet oversees the  multidisciplinary thyroid, parathyroid and adrenal programs at Mount Sinai.

Dr Inabnet competes in triathlons, somehow managing to balance training (swim, bike and run) with work and family time.  Other interests include music, sailing, skiing and fishing.
