Dr Walker is a consultant gastroenterologist at the Royal United Hospital, Bath and practices privately at Circle Bath Hospital.
He qualified with distinction from Imperial College London (Charing Cross and Westminster Medical School) and undertook his gastroenterology training in North West Thames, London. This provided him with broad training in all aspects of gastroenterology and he developed a particular interest in inflammatory bowel disease (Crohn's disease and ulcerative colitis).
He spent three years as a clinical research fellow studying the role of genetics and gut bacteria in the aetiology of inflammatory bowel disease, and was awarded a Doctorate of Medicine in 2011.
Dr Walker has a keen interest in teaching and completed a Postgraduate Certificate in Medical Education at the Royal College of Physicians. He is a Clinical Teacher at the University of Bristol and teaches medical students at the Royal United Hospital, Bath.
Circle Bath Hospital is (JAG) Joint Advisory Group Accredited for its Gastrointestinal Endoscopy.
The JAG Accreditation Scheme is designed to recognise examples of exemplary standards in the sector and denotes formal recognition that an endoscopy unit has the competence to deliver against national measures set out in the Global Rating Scale Standards (GRS), a tool produced to assess how well a unit provides patient centred care.
Dr Walker is married with three children. He enjoys many outdoor interests that include golf, skiing, rugby and cycling.
