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) such as IBS and the use of probiotics and dietary manipulation to manage these conditions.
In 2012 I relocated to Kent and took up my NHS Consultant Post at Darent Valley Hospital. I have held a variety of leadership posts including Lead for Gastroenterology and Clinical Director for Adult Medicine. In 2013 I accredited as a bowel Cancer screening Colonoscopist with the National Bowel Cancer Screening programme and continue to offer screening colonoscopy in my NHS practice as part of the national screening programme. In 2018 I reduced by Managerial responsibilities and took a career break to start my family. Having returned to work, I know hold the post of Chief Clinical Information Officer (CCIO) and Clinical Safety Officer (CSO) for my NHS organisation. In this role I am responsible for and committed to ensuring the safe development, introduction and integration of IT systems to support the delivery of safe and effective patient care.
