About

Nicholas Shaheen is a gastroenterologist and epidemiologist who is probably best known for his groundbreaking research on Barrett鈥檚 esophagus. A major theme of his research has been developing and testing new endoscopic methods for treatment of patients with Barrett鈥檚. He was the principal investigator of a 19 center U.S. trial of radiofrequency ablation for dysplastic Barrett鈥檚 esophagus, demonstrating the efficacy and safety of this procedure. The paper was published in the New England Journal of Medicine. He was also the lead investigator of a 10 center study defining the efficacy of cryotherapy in subjects with Barrett鈥檚 and high-grade dysplasia. These endoscopic technologies have fundamentally changed the care of patients with early esophageal neoplasia. He is also a member of several consortia that are conducting translational studies of Barrett鈥檚 patients.
