Originally from Derbyshire I began my medical training in 1993 at Guy's and St Thomas' hospital graduating in 1999.
After gaining membership of the Royal College of Physicians (MRCP) in 2004 I began training in gastroenterology as an SpR. During this time, I developed a particular interest in inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). My principle research interest is the diagnosis and treatment of irritable bowel syndrome. It is in recognition of my research in this field that I was awarded a research doctorate (MD(res) by Kings College London in 2014. I continue to have an active research and clinical interest in the management of functional gastrointestinal disorders (FGIDs) including IBS and nutrition
