School of Clinical Medicine
During my undergraduate degree and PhD, I developed an interest in radiobiological modelling. My initial work investigated optimisation algorithms in radiobiological modelling for Intensity Modulated RadioTherapy (IMRT). Currently, I enjoy investigating the different factors (see research interests) that influence the way radiation is delivered for treatment, and modelling the impact these changes may have on the radiobiology and patient outcome. I lead the medical physics group at the Ingham Institute for Applied Medical Research which includes medical physics staff at Liverpool and Macarthur Cancer Therapy Centres, as well as postdoctoral research fellows, PhD and undergraduate students. I am involved in the Australian MRI-Linac program which is being developed at the Ingham Institute. I also lead the Computer Assisted Theragnostics (AusCAT) team which is working to link distributed datasets to develop prognostic models for radiotherapy, particularly for situations where randomised clinical trial evidence is limited.

- Member of the expert panel for the review of the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) Training Education And Progression (TEAP) requirements.
- I was involved in establishing the course content at the initiation of the radiobiology course at the University of Sydney as a component of the Master of Medical Physics degree program. Since then, I have taught a nine-hour block of lectures on an introduction to radiobiology and radiobiology modelling each year.
- I have taught a block of lectures in the dosimetry course in the medical physics Master of Medical Physics degree program at the University of Sydney since the initiation of the Master of Medical Physics degree program until 2013.
- I have generally given 2-3 lectures each year as part of the University of Wollongong Master of Medical Physics degree program. These lectures have included radiobiology, imaging, treatment planning and radiation safety.
- I taught the radiobiology course as part of the Medical Radiation Sciences course at the University of Sydney in 1999.
- I have taught a number of the Basic Sciences of Oncology lectures on different subjects including radiobiology modelling, basic interactions and treatment planning reporting.
- I wrote the Electronic Portal Imaging Detector section for the IAEA oncology remote learning multimedia CD.
- I recently gave a presentation on moving towards MRI-linacs looking at the factors to consider and potential systems for the University of Michigan state-wide training lectures for their radiation oncology registrars.
- I have been involved in the CSIRO STEM professionals in schools program since 2010 which links scientists and teachers to encourage the next generation of scientists. I have two partner teachers one at Liverpool girl’s high school where I provide support for teaching the medical physics HSC elective and one at Engadine West Primary school where I have facilitated a number of science activities in different science disciplines across the school.
