Dr. Andras Hajnal is a Professor at the Department of Neural and Behavioral Sciences, Penn State Neuroscience Institute. He completed his M.D. and Ph.D. studies in Medicine and Neuroscience at the University Medical School Pecs, Hungary. His research focuses on the neural mechanisms of appetitive behaviors, such as hedonic eating, substance use, and addiction. Specific areas of his research have investigated how diet-induced obesity produces changes in the brain’s taste and reward systems to perpetuate over-eating and the role of gut-brain factors in regulating reward-guided behaviors.
