Dr. Amy Walker is an ACPSEM certified medical physicist working at the Liverpool and Macarthur Cancer Therapy Centres in a Research & Development role. She completed her undergraduate degree at the University of Wollongong where she then also completed her Ph.D. looking at the impact of MRI geometric distortion on radiotherapy treatment planning. Her research interests continue in the area of MRI utilisation, deformable image registration and adaption for radiotherapy.
