I have a specialist interest in luminal gastroenterology, in particular inflammatory bowel disease and irritable bowel syndrome. Within my NHS role I work in a team treating complex Crohn’s and Ulcerative colitis that I am an experienced endoscopist competent in gastroscopy, flexible sigmoidoscopy, colonoscopy and polyp removal.
I have had experience in three major centres in inflammatory bowel disease and now am part of a team of IBD specialists at the Royal London. I have published in this area and I am actively involved with clinical trials of novel biological therapies. I have experience in specialist IBD endoscopy, novel biologic agents and complex IBD patients.
I have an active interest in irritable bowel syndrome or IBS, in particular in the role that diet and the gut microbiota play in the causes and treatment for this condition. I have published widely in this field in particular in the role that probiotic preparations can have in the treatment of IBS.
I have broad range of endoscopic experience and I am competent in a wide range of diagnostic and therapeutic procedures including in the diagnosis of cancer, ulcers, Barrett’s oesophagus, colitis, Crohn’s disease, diverticular disease and polyps. In particular I specialise in difficult colonoscopy and polypectomy as well as working as a trainer within the NHS .
