Metabolism, Obesity and Diabetes

The Center for Integrative Metabolic and Endocrine Research (CIMER) is a joint research effort of the Departments of Psychiatry and Behavioral Neurosciences, Pathology and Internal Medicine (Endocrinology) that was established to address the world-wide epidemic of obesity and diabetes. CIMER researchers are dedicated to an integrative analysis of neuro/behavioral, cellular and biochemical bases of obesity and obesity-related disorders. CIMER investigators conduct basic research with the goal of identifying and developing new molecular targets for treatment of metabolic diseases.
 

CIMER Principal Investigators
