I am a clinician-investigator specializing in the field of celiac disease and in 2001 I founded the Celiac Disease Center at Columbia University Medical Center. The Center now includes adult and pediatric gastroenterologists, dieticians, and research coordinators; and has active research collaborations worldwide to study the epidemiology, clinical manifestations, and the pathophysiological mechanisms of celiac disease. I have authored a book, “Celiac disease, a hidden epidemic” and have co-authored more than 100 peer-reviewed publications on the topic of celiac disease, including epidemiological investigations, studies of associated diseases, pathophysiology, and clinical trials of non-dietary drug therapy.
