Gary Royle is professor of Medical Radiation Physics within the department of Medical Physics and Bioengineering and leads a proton therapy research team. Research interests include the development of imaging and detection techniques for cancer treatments, namely proton therapy and advanced radiotherapy. The purpose of the imaging techniques is for either image guided treatments, treatment verification or to assess the effectiveness of the cancer treatment. Project areas include development of novel imaging techniques, instrumentation and computer simulation. Projects are performed in collaboration with clinical colleagues in the radiotherapy department at UCL hospital. Proton therapy projects are performed in association with clinical proton therapy centres in the UK and overseas.
