I was appointed as a Consultant Surgeon at University Hospital Southampton in 2002, after surgical training in the North West of England, and a fellowship at the Princess Alexandra Hospital in Brisbane, Australia.

I provide a comprehensive service in the area of upper gastrointestinal disease and enjoy working alongside other specialist colleagues in the management of particularly challenging and complex problems. As well as managing oesophageal and gastric cancers, and my obesity surgery practice, I also perform a wide variety of other laparoscopic surgery including cholecystectomy, hernia repair and anti-reflux surgery.

I have been a member of the bariatric (obesity) surgical team in Southampton that has now performed over 2,000 procedures since it was established in 2004. I offer laparoscopic gastric banding, sleeve gastrectomy, laparoscopic roux Y gastric bypass and revision surgery.

I am passionate about improving outcomes for patients and contributing to building high quality evidence to underpin clinical practice.

I am also a NICE advisor for Upper GI surgery and a member of the Council of the British Obesity and Metabolic Surgery Society.

I am an investigator on three large ongoing randomized studies:

  1. BY-BAND-SLEEVE. £4.2m HTA funded randomised comparison of the three commonly weight loss procedures
  2. Endobarrier. £2.4m EME funded randomized study of this novel intervention for type 2 diabetes
  3. ROMIO. HTA funded randomised comparison of open and minimal access oesophagectomy


A two-consultant approach is a safe and efficient strategy to adopt during the learning curve for laparoscopic Roux-en-Y gastric bypass: our results in the first 100 procedures
