I am a consultant gastroenterologist and specialist endoscopist at St Mark’s Hospital, Harrow, an internationally recognised centre of excellence for intestinal disorders and endoscopy. I am the clinical lead for endoscopy and my specialist interests include general and luminal gastroenterology, diagnostic and therapeutic endoscopy, bowel cancer prevention & screening endoscopy (nationally accredited bowel cancer screening colonoscopist), video capsule endoscopy, double-balloon enteroscopy, inflammatory bowel disease and small bowel diseases.
In 2007 I was awarded a Cancer Research UK Clinical Research Fellowship, and gained a PhD in 2012 from University College, London for my research into the biology of gastrointestinal tumours. My current academic interests include the evolution of pre-cancerous growths within the gut and the diagnosis and treatment of small bowel diseases.
Having qualified from Imperial College Medical School in 2002, I undertook my specialist gastroenterology training within London from 2005-2013. I then completed a fellowship in advanced and small bowel endoscopy at St Mark’s Hospital before being appointed to the Consultant staff in 2014.
