Professional profile

I have been a consultant surgeon in Portsmouth for 20 years, with a specialist interest in colorectal surgery and a major commitment to emergency abdominal surgery. My ongoing clinical aim is to improve the care and outcomes of patients with colorectal disease, especially following colorectal surgery.

I have been instrumental in the provision of a Surgical High Care Unit, Enhanced Recovery Programme, Surgical Skills Lab and National Training Programme in laparoscopic colorectal cancer surgery in Portsmouth. My outcomes for cancer surgery are submitted independently to the National Bowel Cancer Audit and are within the expected range.

Benign and malignant colorectal disease account for the majority of my NHS and private practice. My private practice is based at Spire Portsmouth Hospital, where I have a weekly clinic, operating sessions and colonoscopy facilities.

After medical school at University College Dublin, I trained to FRCSI in Ireland. I then undertook a research fellowship at Boston University. I returned as a lecturer in surgery in Sheffield and did higher surgical training in Bristol and the South West.

I completed training in specialist coloproctology at St Mark's Hospital, London and in laparoscopic colorectal cancer surgery within the Lapco National Training Programme. I have written 35 peer-reviewed papers and four book chapters.

In 1997 I obtained first place in the Intercollegiate Examination - FRCSI(Gen) and the Gold Medal of the Association of Surgery of Great Britain and Ireland.
