Prof Siva is a radiation oncologist, a clinician academic, and the first Radiation Oncologist to be awarded the prestigious Cancer Council Victoria Colebatch Fellowship (2020). Prior to this award, he held a NHMRC Early Career Fellowship. He is the lead clinician and director of the Stereotactic Ablative Body Radiotherapy (SABR) program at the Peter MacCallum Cancer Centre, and is internationally recognised for his work in high-technology radiotherapy delivery and implementation in novel indications. He published the first original research from Australia on the use of SABR and his contributions to the field include pioneering research of kidney SABR, single fraction SABR, and radio/immunotherapy combinations. His other major research interests are innovative radiotherapy delivery and functional imaging in radiation therapy. Prof Siva has designed and led multiple clinical trials, in the fields of oligometastases, lung, prostate and kidney cancers and is the chair of five TROG trials.
