Prof. John Hermon-Taylor is a molecular scientist, retired surgeon and internationally renowned Crohn’s Disease expert whose research into Mycobacterium avium subspecies paratuberculosis (MAP) and its relationship to Crohn’s Disease has spanned over 30 years.

John qualified as a doctor from Cambridge University in 1960 and went on to obtain Fellowship of the Royal College of Surgeons in 1963. He was appointed to the Chair of Surgery at St George’s Medical School, London in 1976. From this time, John dedicated himself to the care of people with Crohn’s Disease. Many of his former patients attest to his kindness, generosity and personal approach as well as his wisdom and skill as a surgeon. His determination to help his patients led his career down a research pathway. He led a team of scientists at St. George’s, focussed on the causation of Crohn’s Disease and increasingly on the involvement of MAP, which he believes to be the predominant cause of Crohn’s. He retired from the practise of surgery in 2002, to focus full-time on his research.

Between 1997 and 2007 he developed a modern therapeutic vaccine against MAP (together with Dr Tim Bull at St George’s and Prof. Sarah Gilbert at Oxford University) designed to treat Crohn’s. He believes that the vaccine holds the best hope of Crohn’s cure we have ever had.

In 2008 he moved to King’s College London where he continues to work full-time as a Visiting Professor in the gastrointestinal research group run by Dr Jeremy Sanderson.

He is currently seeking the funding to carry out a trial of the vaccine in people with Crohn’s Disease, whilst working on the completion of a much-needed diagnostic test for MAP in humans.
