After completing my PhD under Prof Tom MacDonald (ICMS), I spent several years researching inflammatory bowel disease and the immunology of infectious diseases of the gut. This eventually led me to work on stem cell biology within the human gastrointestinal tract with Professor Sir Nicholas Wright and Professor Malcolm Alison. I re-joined Barts and the London in November 2008 and have developed my own research interests around the development of premalignant disease into cancer.
