M. Yanina Pepino

Dr. Pepino is a  Professor of Ingestive Behavior at the Department of Food Science and Human Nutrition, and the Division of Nutritional Sciences and  in Carle Illinois College of Medicine.  She received her B.S. degree in Pharmaceutical Chemistry, from the Faculty of Chemical Sciences, National University of Córdoba, Argentina, in 1995 and a Ph. D.  in Chemistry from the same university in 2001.  After completing her graduate degree, she was a post-doctoral research fellow at Monell Center in Philadelphia. Before joining the University of Illinois, she was a Research Assistant Professor at the Center for Human Nutrition, Washington University School of Medicine. In recent years, her research has focused on individual differences in taste perception, food preferences, and ingestive behavior. Among the individual differences, she has a particular interest in studying those related to obesity and addiction.  In 2011, Dr. Pepino was the recipient of the 20th Annual Moskowitz Jacobs Award for Research in Psychophysics of Human Taste and Smell, a prestigious award given by the International Association for Chemoreception Sciences.  Dr. Pepino’s current research interests include understanding 1) the effect of bariatric surgery-induced weight loss on flavor perception and eating and drinking behavior; 2) the effect of non-caloric sweeteners on taste preference and glucose homeostasis, and 3) taste and smell function in clinical populations.
