About the expert

Focus: Intestinal stem cell regeneration and fasting

Dr. Omer Yilmaz is an associate professor at MIT specializing in intestinal stem cell biology. His lab studies how diet, aging, and metabolic signals influence stem cell function and cancer risk in the gut. He has published landmark research on fasting-induced intestinal stem cell regeneration, including studies showing that a 24-hour fast doubles ISC regenerative capacity.
