Biography
Clinical interests in breast, lung, and prostate cancers.
Michael is a Professor of Radiation Oncology whose work spans breast, prostate, and lung cancers, with a particular focus on harnessing modern radiation therapy to improve cancer control while minimising treatment-related side effects. In prostate cancer, he pioneered the introduction of rectal spacers in Australia, an innovation that has significantly enhanced the safety of radiation therapy for countless patients.
He completed his MBBS with Honours at Monash University in 1991 and was awarded his Fellowship of the Royal Australian and New Zealand College of Radiologists (FRANZCR) in 1999. He then spent two years as a research fellow in the DNA Research Laboratory at the Peter MacCallum Cancer Centre, during which he was both an NHMRC Scholar and a Sir Edward ‘Weary’ Dunlop Research Fellow. Michael later earned his Doctor of Medical Science (DMedSc) from the University of Melbourne.
A passionate researcher, Michael has authored more than 130 publications and supervises multiple PhD candidates. He began his consultant career in 2000 with GenesisCare and now consults at the Ringwood and Peninsula GenesisCare Radiation Oncology Centres. He also serves as an honorary radiation oncologist at Maroondah Hospital (Eastern Health) and as the breast cancer radiation oncology lead at the Olivia Newton-John Cancer and Wellness Centre. In 2025, he was appointed the Medical Director of Radiation Oncology at GenesisCare.
Across his clinical, research, and leadership roles, Michael remains dedicated to advancing evidence-based, patient-centred radiation oncology.
