A/Prof Santosh Sanagapalli is a gastroenterologist, clinician researcher, and specialist in swallowing disorders. He undertook a clinical research fellowship in gastrointestinal physiology at University College London and completed his PhD at the University of Sydney. He established the Centre for Swallowing & Oesophageal Disorders at St Vincent’s Hospital Sydney where he runs an active clinical research program. His research is primarily focused on advancing the methodology and utility of the technology used to investigate swallowing disorders and reflux, including high-resolution manometry, ambulatory reflux monitoring, endoscopy and barium oesophagography.
