Short Bio

Dr. Marcus Harbord

I am a consultant physician and gastroenterologist, working at the Chelsea and Westminster Hospital, specialising in inflammatory bowel disease (IBD), colorectal cancer, and colonoscopy; nutrition and the irritable bowel syndrome; and indigestion. I have full accreditation in general medicine, gastroenterology, hepatology and endoscopy. I have been the lead clinician of the gastroenterology department at the Chelsea and Westminster Hospital between 2007 and 2016; and previously a consultant at the Royal Free Hospital, London.

I attended Eton College from 1981 to 1985, then studied medicine at St. Mary’s Hospital, London between 1986 and 1992. I received further training at UCL, Royal Free Hospital and St. Mark’s Hospital, during which time I passed my USA medical exams, becoming an accredited UK gastroenterology specialist in 2002, when I was awarded a PhD degree for my research into acute inflammation in Crohn’s disease.

I have published widely on inflammatory bowel disease. I have been an editorial board member of the journal Inflammatory Bowel Disease; chairman of the new consultants’ committee and a council member at the Royal College of Physicians from 2009 to 2011; an elected member of the European Crohn’s and Colitis Organisation (ECCO) guidelines committee between 2013 and 2016 and its chairman during 2015-16.

I have written a 1st edition gastroenterology textbook, entitled Emergencies in Gastroenterology and Hepatology, published by Oxford University Press in August 2013.

I am probably most proud of having created ECCO’s e-Guide, an on-line algorithmic resource that has provided IBD education to more than 20,000 healthcare professionals across the world. Currently I am principle investigator for the UK IBD twin registry and biobank, and in charge of ECCO’s e-Guide.

I practice an evidence-based yet holistic approach. My homes are in London and Lisbon. As of 2019 I am leading a MedTech project to provide medical information to the poorest peoples in the world.
