Biography

I graduated from St Joseph University, Beirut, Lebanon in 1998, then completed my training in Internal Medicine and Gastroenterology at UMDNJ/Robert Wood Johnson Medical school. I joined the Digestive Diseases section at Yale in 2012, worked as full time faculty until August 2015. I have two areas of interests, screening for colon cancer and functional bowel diseases. As general gastroenterologist, I treat patients with a wide range of digestive symptoms including reflux, ulcers, irritable bowel syndrome. I currently work at Yale on a part time basis, mainly attending on the inpatient gastroenterology service.
