Tomas Kron was born and educated in Germany. After his PhD he migrated to Australia in 1989 where he commenced his career in radiotherapy physics. From 2001 to 2005 he moved to Canada where he worked at the London Regional Cancer Centre on the commissioning of one of the first tomotherapy units. In 2005, Tomas became principal research physicist at Peter MacCallum Cancer Centre in Melbourne, Australia where he now is Director of Physical Sciences. Tomas holds academic honorary appointments on a professorial level at Wollongong, RMIT and Monash Universities. He has an interest in dosimetry of ionising radiation, image guided radiotherapy and clinical trials as a tool to introduce technology. This is demonstrated by more than 80 invited conference presentations and 250 papers in refereed journals. In 2014 he was awarded an Order of Australia Medal (OAM) for services to medicine, research and education.
