Graduated MB ChB in 1971 from Leeds Medical School having intercalated Hons BSc in Biochemistry in Relation to Medicine in 1968. Trained in general medicine and gastroenterology at Hope Hospital, Salford, Manchester Royal Infirmary and Royal Victoria Infirmary, Newcastle upon Tyne. Gained MRCP (UK) in 1974 and elected FRCP (London) in 1993. Awarded MD (1980) and PhD (1987) for research into small intestinal and colonic transport physiology in health and disease. Gained further training in research in the Section of Digestive Diseases, Department of Internal Medicine, Yale University, USA (1981-1983), leading to award of prestigious Medical Research Council Senior Clinical Fellowship to enable establishment of independent research programme in UK (1983-1989). 30-year track record of research funded from a variety of sources, including Medical Research Council, Wellcome Trust, Royal Society, and British Heart Foundation. Currently collaborate with colleagues in Leeds and USA.
Areas of interest
Dyspepsia (indigestion); Investigation and management of ulcerative colitis and Crohn's disease and other diseases / disorders causing diarrhoea, constipation and abdominal pain; Functional bowel disorders; Gastro-intestinal oncology; Gastro-intestinal endoscopy (gastroscopy and colonoscopy +/- colonic polypectomy)
Current NHS consultant posts held

Zero rates for re-admission, infection and mortality after upper and lower gastrointestinal endoscopies. 95% completion rate for colonoscopy. Colonic polyp detection rate consistent with national standards. High rate of re-referrals in both private and NHS sectors when patients have recurrence of 'old' symptoms or develop new ones. If required, prompt transfer of un-insured private patients to NHS clinic for consultant-delivered investigations and management.
