• Dr. Sugandha is a Clinical Associate Professor of Medicine, Division of Gastroenterology. He completed a Bachelors of Medicine and Surgery at Madras University in India and then a fellowship in Internal Medicine specializing in Gastroenterology at Christian Medical College in Vellore, India. Between 2000 and 2004 he was a Consultant in the Department of Gastroenterology at Christian Medical College. In 2005 he became a Staff Gastroenterologist at the University Hospital of Basel, Switzerland, until he joined the UAB in 2008.

    He is Board certified in Internal Medicine and Gastroenterology. He directs the UAB complicated Barrett’s esophagus and early esophageal cancer program. His clinical interests include esophageal and small bowel disorders. He performs radiofrequency ablation, deep enteroscopy, advanced endoscopic imaging, screening for colorectal cancer, endoscopic mucosal resection and therapies for GI bleeding. His research focuses on endoscopic treatment outcomes of Barrett’s esophagus and obscure GI bleeding and he collaborates with scientists and physicians in cell biology and mucosal immunology to better understand esophageal pathobiology. In addition, he oversees research projects with residents and fellows within the GI division
