Eating Behavior, Obesity and Diabetes Laboratory

The Eating Behavior, Obesity and Diabetes Laboratory is led by Joyce Corsica, PhD, and Megan Hood, PhD, with significant contributions from our clinical health psychology postdoctoral fellows and residents as well as our research assistants.

We investigate behavioral and psychological factors in metabolic conditions, particularly obesity and diabetes, and apply this knowledge to intervention development efforts to improve treatment of these conditions and quality of life in the patients who have them.
