Researching the Metabolic Brain

My research focuses on how the brain senses nutritional status and regulates feeding behavior, metabolism, and body weight. Our work led to the discovery that the hormone FGF21 targets the brain to coordinate the adaptive response to protein restriction, thereby regulating growth, metabolism, food choice, and motivation.
