About me

Dr Gaya qualified at St George’s Hospital Medical School (University of London) where he was awarded a distinction and several academic prizes. He trained in Clinical Oncology at Imperial College and St Bartholomew’s Hospital and subsequently undertook a Cancer Research UK MD Fellowship at University College London.

Dr Gaya treats solid tumours using chemotherapy, radiotherapy, immunotherapy and biological therapies – He treats gastrointestinal cancers – cancers of the oesophagus, stomach, pancreas, liver, colon, rectum and anus. Dr Gaya’s main research interests are functional cancer imaging, looking for ways to assess response to treatment much earlier. He is also involved in the clinical development of immunotherapies such as IMM-101, recently published as the IMAGE-1 trial, and is now looking to combine radiotherapy with immunotherapy.

He was heavily involved with the implementation of the latest radiotherapy techniques in the UK such as SABR (SBRT), and is looking forward to the introduction of proton therapy to the UK in 2018 as this has potential advantages for some gastrointestinal cancers. He was one of the first UK oncologists to use the CyberKnife, now almost 10 years ago. He has published widely in peer-reviewed journals. He is a principle investigator on a number of national and international clinical trials, sits on the board of directors of the Radiosurgery Society (, and is on the editorial review board for the Cureus journal (
