Professional background

I am a consultant gastroenterologist specialising in gastroesophageal reflux disease, Barrett’s oesophagus and upper gastrointestinal cancer. I was the lead clinician for Upper Gastrointestinal Cancer at UCLH from 2001-8. I graduated from University College London Medical School in 1987 and obtained my PhD at the Royal Postgraduate Medical School, Hammersmith Hospital. I was appointed as a Consultant Gastroenterologist at UCH and Senior Lecturer in Laser Medicine at the National Medical Laser Centre, UCL in 1999. I have previously chaired the North London Cancer Network Upper Gastrointestinal Tumour Board.

I am active in clinical translational research to prevent oesophageal cancer, with particular interests in photodynamic therapy and novel optical biopsy techniques. I am the chief investigator for the UK National HALO Patient Registry.

Research interests

  • Gastroesophageal reflux disease
  • Barrett’s oesophagus
  • Oesophageal cancer 
  • Nove endoscopic therapies including laser therapy, photodynamic therapy and HALO radiofrequency ablation.
