I am a Consultant Gastroenterologist and a colorectal cancer screening colonoscopist. Within Gastroenterology, I have an interest in acid reflux and minimally invasive diagnostics and therapy and I am an endoscopy trainer. I have been a bowel cancer screening colonoscopist since early 2014 and I am now a mentor within the National Bowel Cancer Screening Programme.

Until recently, I was Lead Clinician for Endoscopy and Gastroenterology and in the past I have been Lead Clinician for Digestive Diseases and General Surgery as well as Endoscopy Training Lead. I am now focusing on cancer screening and minimally invasive diagnostic techniques.

I set up and I run the local capsule endoscopy service for investigation of the small bowel examining for causes of abdominal pain and anaemia. I also set up and run local pH and manometry services for the treatment of acid reflux and swallowing disorders.

I trained at St Bartholomew's Hospital in London after previously obtaining a first class honours degree in epidemiology and statistics from the University of London before choosing a career in Gastroenterology. Subsequently I was awarded a PhD from University College London for studies into diagnosis of gastro-oesophageal reflux disease, Barrett's oesophagus and the development of gastrointestinal cancer and their treatment.
