Matt Hayes is an Associate Professor of Nutritional Neuroscience, and Vice Chair for Basic and Translational Neuroscience Research in the Department of Psychiatry, Perelman School of Medicine at the University of Pennsylvania. Dr. Hayes earned his Ph.D. in Nutritional Sciences from The Pennsylvania State University and conducted his postdoctoral fellowship in psychology and neuroscience at The University of Pennsylvania. Dr. Hayes is considered a leading expert on the neuroendocrine systems that regulate energy balance. In particular, the Hayes laboratory focusses their research efforts extensively on understanding the neural, behavioral, cellular, molecular, and physiological mechanisms by which hormones, such as glucagon-like peptide-1, amylin and leptin regulate food intake and body weight through action in the mesolimbic reward system and caudal brainstem. In addition, the Hayes laboratory is also examining whether these energy balance-relevant neuroendocrine signaling pathways play a critical role in modulating drug taking and seeking using rodent and shrew models. These basic science research efforts are conducted with the intention that they will translate into improved pharmacological / behavioral treatments for obesity, diabetes, drug abuse and co-morbid diseases.

Dr. Hayes has received numerous honors and awards from The Obesity Society, the Society for the Study of Ingestive Behavior and his alma mater, The Pennsylvania State University. Matt has served as program chair and as an executive board member and scientific advisor for multiple international scientific societies, industry partners and non-profit organizations dedicated towards neuroscience, nutrition, diabetes and obesity research and clinical care. As an educator, Dr. Hayes holds a secondary appointment in the School of Nursing where he teaches core courses for the Nutrition Major at Penn.
