Neurobiology of obesity and diabetesGastric-bypass surgery

Dr. Schwartz studies how the gut and the brain act together to determine how much people eat. He has identified sites in the gastrointestinal tract and brain that detect nutrients and has discovered how these regions are linked to food intake, obesity and diabetes. He also studies gastric-bypass surgery and the key neural and hormonal mechanisms responsible for the significant and long-lasting improvements in body weight, food intake and diabetes following the procedure.

Dr. Schwartz is Director of the Einstein-Mount Sinai Diabetes Research Center Animal Physiology Core at Einstein and Director of the Animal Phenotyping Core of the Columbia University- Einstein New York Obesity Research Center. He also serves on multiple NIH study sections and on scientific grant review panels of the United States Department of Veterans Affairs, American Diabetes Association, Endocrine Fellows Foundation and Obesity Society. He is a member of the editorial boards of several journals, including Diabetes, Endocrinology and serves as an associate editor of the American Journal of Physiology, Endocrinology & Metabolism Section.
