Dr. Sabrina Diano is a Tenure Professor in Departments of OB/GYN & Reproductive Sciences, Neurobiology and Comparative Medicine at the Yale University School of Medicine. She is also part of the Integrative Cell Signaling and Neurobiology of Metabolism (ICSNM), and Interdepartmental Neuroscience Program here at Yale. She graduated with honors from the University of Naples “Federico II”, Naples, Italy. She conducted her post doctoral studies here at Yale where she became faculty in 2000.

Her research focuses on CNS (hypothalamic) mechanisms relating to the regulation of energy and glucose homeostasis. Her studies on hypothalamic inter- and intra-cellular mechanisms that regulates energy metabolism add critical information to the current understanding of the central regulation of energy and glucose homeostasis and how alterations in stored energy are sensed in the hypothalamus. The results of her research have important implications for understanding the pathogenesis of metabolic syndrome, obesity and type 2 diabetes, disorders that are the leading cause of morbidity and mortality in the U.S., and the developed world in general, with the highest financial burden on the National economy.
