Biography

I am passionate about improving research in the field of advanced endoscopy. My interests have centered largely around the theory and application of in-vivo diagnostic techniques in the upper and lower gastrointestinal tract. I was part of the BADCAT multidisciplinary taskforce investigating the diagnosis and management of high grade dysplasia within Barrett’s, and was part of a task force developing the ESGE guidelines for the application of in-vivo diagnostic techniques in the detection and evaluation of colonic polyps. I also research improving techniques of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD).

I peer review for most of the main gastroenterology journals and present frequently in many of the world gastroenterology conferences.

Research Interests

  • Use of acetic acid in the oesophagus to diagnose neoplasia in Barrett’s
  • Use of electronic imaging techniques for the evaluation of colonic neoplasia
  • Use of chromoendoscopy for the evaluation of colonic neoplasia
  • Improving colonoscopy
  • Advances in endoscopic resectional techniques (upper and lower gastrointestinal)

Currently I am co-investigator in the ABBA study investigating acetic acid gastroscopy for Barrett’s surveillance (PI for Portsmouth). This is an RFPB funded tandem endoscopy feasibility study which aims to assess whether targeted biopsies can replace the current approach of mapping biopsies for detection of neoplasia within Barrett’s in a surveillance population.
