I have been a Consultant Gastroenterologist at Addenbrooke's Hospital in Cambridge since 2001 and clinical lead for gastroenterology since 2004. I have a particular interest and expertise in diagnostic gastroenterology, including endoscopy and colonoscopy, and management of Crohn's disease, ulcerative colitis, coeliac disease and irritable bowel syndrome (IBS). With a caring and friendly manner in the clinic and outside, I undertake all private diagnostic endoscopy / colonoscopy myself and have extensive experience of the full range of medical and dietary therapies for gastroenterological disease.I undertake all endoscopy myself, and by working closely with colleagues in radiology, pathology, surgery and dietetics, I ensure your appropriate investigation and treatment whatever the cause of your symptoms. I have a particular clinical and research interest in Crohn's disease and ulcerative colitis, for which I lead internationally renowned research groups focused on determinants of causation and disease course.I have been director and clinical lead for Gastroenterology at Addenbrooke's Hospital for the last 12 years and am actively involved as chair of the the BSG IBD Clinical Research Group and chair of the UK IBD Genetics Consortium.
