Matthew Ricci, Ph.D.
V.P./Science Director
Dr. Ricci received his Ph.D. in Nutritional Sciences from Rutgers University in 2000, where he studied leptin secretion from human adipose tissue in vitro with Susan K. Fried, Ph.D. He then joined the lab of Barry E. Levin, MD as a Postdoctoral Research Fellow at the VA Medical Center in East Orange, NJ. During his postdoctoral training, he studied the development of diet-induced obesity in selectively-bred strains of Sprague-Dawley rats that either become obese or remain lean when exposed to a high-fat diet.
