Personal Statement

I am pleased and excited to be a part of the Weill Cornell Medicine faculty as Director of Motility Laboratories for the Division of Gastroenterology at the Jay Monahan Center for Gastrointestinal Health. My clinical practice is devoted to caring for patients with esophageal disease such as complex swallowing and motility disorders, achalasia, refractory GERD, unexplained chest pain, eosinophilic esophagitis, Barrett’s esophagus and esophageal cancer.   My research interests include pharmacodynamics effects of proton pump inhibitors, optimal use of reflux monitoring, esophageal motility and Barrett’s esophagus. I am dedicated to providing excellent, responsive and comprehensive care for my patients and advancing research in esophageal disease.
