Bhaskar Banerjee, MD

  • Professor of Medicine, Optical Sciences and Biomedical Engineering
  • Program Director, Gastroenterology Fellowship

Dr. Banerjee served as chief of the Division of Gastroenterology from November 2008 to November 2015. He obtained his medical degree from the University of London, UK, followed by postgraduate training in internal medicine and gastroenterology at the University of Connecticut School of Medicine. Prior to joining the University of Arizona, Dr. Banerjee was in the Division of Gastroenterology at Washington University in Saint Louis for nine years, during which time he was promoted to professor of medicine. Dr. Banerjee's research interest is in the development of new optical techniques for the detection and treatment of gastrointestinal disorders. His clinical interests include gastro-esophageal reflux disease, Barrett’s esophagus, peptic ulcer disease, screening and surveillance of colon cancer, functional bowel disorders and diseases of the small intestine. Dr. Banerjee is the editor of a textbook, Nutritional Management of Digestive Disorders. He holds joint appointments as a professor of optical sciences and biomedical engineering. He is a member of the Arizona Cancer Center and the Graduate Inter-Disciplinary Program. Dr. Banerjee is board certified in gastroenterology and internal medicine. 

Research Interests: 

"My research interest is in bringing novel optical and engineering solutions to gastrointestinal disorders. I work closely with optical scientists, biomedical engineers, chemists and molecular biologists to develop novel methods of detecting cancer and other diseases before they can be seen by the naked eye. We are developing unique instruments that see in multiple directions at the same time as well as optical techniques that instantly reveal structural and functional changes in disease states that are invisible to the human eye. These methods will help detect disorders at an earlier and easily treatable stage, in real-time and at the point of care, without the use of dyes, stains or other chemicals (label-free imaging).”
