Biographical details

I am a medical physicist with a career history in both clinical and academic settings. I completed a BSc (Hons) degree in Physics at the University of Manchester, UK. Following this I completed an MSC. in Medical Physics and the Institute of Physics in Engineering and Medicine (IPEM) training scheme for Clinical Scientists. During this training I completed placements in Diagnostic Radiology, Radiotherapy and Nuclear Medicine. I worked for 18 months as a Clinical Scientist in Radiotherapy at Mount Vernon Hospital in North London, UK before beginning a PhD at City University. I completed my PhD in 2006 with my thesis entitled "The characterisation of five classifications of breast tissue using x-ray scattering properties'. I gained a position as a Post-doctoral Research Assistant at City University for 2 years, before making the move to Australia to begin a lectureship at the University of Sydney. I am still involved with an international collaboration continuing the work that I started during my PhD and am also involved in research collaborations within the Faculty of Health Sciences, UTS and at Westmead Hospital.
