A cancer diagnosis is usually extremely confronting – guiding patients through their treatment options is essential.

Special clinical interests in lung and breast cancer

Tim received his undergraduate medical degree from the University of Western Australia in 2004 with honours. He spent his junior medical career at Royal Perth Hospital including rotations to Swan Districts, Bunbury and Kalgoorlie. In 2010, he moved to Victoria and undertook advanced training in medical oncology at Geelong Hospital (Barwon Health) and at St Vincent’s Hospital in Melbourne.

After practicing medical oncology across Victoria, regional New South Wales and Queensland, Tim returned home to Perth in 2014, working initially at Royal Perth Hospital and Rockingham General Hospital. Deciding to concentrate fully on private practice, Tim left these positions and joined GenesisCare in Joondalup in 2017.

Tim’s professional interests include clinical trials, to improve the treatment options of future cancer patients, and the undergraduate and postgraduate training of health care professionals.

Tim has completed a doctoral thesis on lung cancer and had his first major work, ‘The clinical relevance of pathologic subtypes in metastatic lung adenocarcinoma,’ published in the Journal of Thoracic Oncology in 2014. He is actively involved in cooperative clinical trials groups including the Australasian Lung Cancer Trials Group (ALTG), the Australia and New Zealand Breast Cancer Trials Group (ANZBCTG) and the Australasian Gastro-Intestinal Trials Group (AGITG).

Tim is married with three children (although his wife sometimes asserts that he is the oldest child!). He has particular skills in redesigning the layout of his son’s wooden train set, and is patiently learning how to properly use hair ties for his daughter. He enjoys watching Formula 1 motor racing in his spare time. Tim is a full-time doctor, an amateur comedian, and usually doesn’t speak in the third person!
