I am an experienced gastroenterologist, having qualified as a doctor in 2003 and appointed as a consultant in 2017. I specialise in the diagnosis and treatment of all gastrointestinal conditions and am an expert in the management of functional bowel disorders such as functional dyspepsia and gastroparesis.

I have a particular interest in clinical nutrition, malabsorptive conditions and oesophageal disorders such as gastro-oesophageal reflux, oesophageal dysmotility, eosinophilic oesophagitis and Barrett's oesophagus.

I have extensive experience and expertise in performing gastroscopy, flexible sigmoidoscopy and colonoscopy and my key performance indicators are excellent.

I am an accredited endoscopy trainer and have performed over 3,000 colonoscopies and 5,000 gastroscopies. I was the clinical lead for nutrition in Cardiff for six years and have extensive experience in managing patients with intestinal failure.

I was head of the Welsh intestinal failure service (based at the University Hospital of Wales in Cardiff) between 2017 and 2024. In 2024, I moved to the Royal Gwent hospital to pursue an advanced endoscopy role and I am accrediting to be a bowel screening Wales colonoscopist.

I have an interest in medical education and was the educational faculty lead for medicine in Cardiff and an examiner for Cardiff University medical school.

I have had a number of original research and review articles published in international gastroenterology journals.
