Professional profile

My practice involves the diagnosis and management of all aspects of gastroenterology and liver disease including diagnostic and therapeutic endoscopy and colonoscopy. I am an accredited national bowel cancer screening colonoscopist and have a special interest in therapeutic colonoscopy and endoscopy training as well as inflammatory bowel diseases, clostridium difficile infection and faecal transplantation.

Having graduated from the University of Birmingham in 2002, I completed my specialist training in gastroenterology and general internal medicine on the North West Thames training rotation and was awarded a certificate of completion of training in gastroenterology and general internal medicine in August 2015.

I worked as a specialist registrar for four years at St Mark's Hospital, including a period of research and an advanced endoscopy fellowship. I also worked at Chelsea and Westminster and West Herts Hospitals before being appointed to my consultant post at West Herts in July 2016.

I was awarded a Doctor of Philosophy PhD from Imperial College London in 2015 following my period of research into the interactions between the immune system and the gut microbiota causing inflammatory bowel diseases, specifically looking at pouchitis. As a part of my research I ran the first UK pilot study of faecal transplantation for inflammatory bowel diseases.
