I am a clinical researcher at the UCL Cancer Institute specializing in gastrointestinal (GI) medical oncology. I trained in medicine at Oxford and University College London, and specialised in Medical Oncology at the Middlesex, Mount Vernon and Royal Marsden Hospitals. I hold a PhD in gene therapy from the Institute of Cancer Research. I lead the National Cancer Research Institute subgroup in upper GI malignancy, and multiple laboratory collaborations investigating the biology of cancers. I have led a number of landmark studies including the ABC-02 and New EPOC studies. I am chief investigator on 3 studies in the National Cancer Research Institute (NCRI) upper GI portfolio and serve on a number of committees including those for the NCRI (upper GI and colorectal),  American Society of Clinical Oncology faculty and National Institute of Clinical Excellence. I have a clinical practice at the Princess Alexandra and University College London Hospitals NHS Trusts.
