Children with Cancer UK Research Fellow
University College London, UK
My research area covers advanced MRI techniques for improved diagnosis and monitoring of treatment response in paediatric cancer. I specialize in the development of new imaging techniques for measuring the cellular and vascular structure of paediatric brain tumours. I am currently leading the integration of these techniques into clinical practice at Great Ormond Street Children's Hospital. Using these techniques, we can monitor the blood supply to a tumour, which will have a strong influence on the efficacy of drug delivery. Changes in the tumour microstructure as a response to treatment can also be measured.
