Our laboratory's overarching goal is to identify and characterize the neural signaling pathways controlling for food intake and body weight regulation in an effort to treat obesity and associated co-morbidities. To this end, our research examines the behavioral, intracellular, neuronal, and endocrine mechanisms governing energy balance and how these processes are dysregulated in obesity.
