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, and biological therapies - His main focus is on colorectal cancer, cancers of the oesophagus, stomach, pancreas, liver, lung and prostate cancer.
Dr Gaya’s main research interests are functional cancer imaging, where he is looking for ways to assess response to treatment much earlier, and techniques for assessing blood flow and oxygen levels within cancers. He is also interested in developing drug treatments that can cut off the blood supply to cancers, or stop cancers making new blood vessels.
He is heavily involved with the implementation of the latest radiotherapy techniques such as IMRT, IGRT and Tomotherapy, combining targeted or anti-vascular drugs with radiotherapy, and stereotactic body radiosurgery. He is one of the first UK doctors to use CyberKnife robotic radiosurgery. He has published widely in peer-reviewed journals, and is currently lead clinical oncologist for audit and clinical governance at Guy’s and St Thomas’ NHS Foundation Trust. He is a principle investigator on a number of national and international clinical trials.
