Rate My Professor Peter Greer

Conjoint Professor Peter Greer holds a position in the School of Science (Physics) at the University of Newcastle and serves as Director of Medical Physics at Calvary Mater Newcastle Hospital since 2023, having led medical physics research at the hospital and university for the previous 15 years. He earned his PhD in Medical Physics from the University of Adelaide in 2001 and an MSc in medical physics in New Zealand. Greer has extensive experience as a radiation oncology medical physicist, working in New Zealand, Canada, and Australia. As Chief Medical Physicist at Calvary Mater Newcastle Hospital, he supervises 20 staff members and directs a medical physics research group. He has supervised 22 PhD students, published 215 peer-reviewed articles, and served as chief investigator on grants totaling $20 million.

Greer's research focuses on advancing radiation therapy through innovations in MRI-based treatment planning, including MRI-only radiotherapy and synthetic CT generation; dose verification and in vivo dosimetry using electronic portal imaging devices (EPID); motion management; and adaptive radiotherapy, particularly for prostate cancer. Key publications include 'A Multi-Center Prospective Study for Implementation of an MRI-Only Prostate Treatment Planning Workflow' (Frontiers in Oncology, 2020), 'Remote EPID-Based Dosimetric Auditing Using DVH Patient Dose Analysis' (Physics in Medicine and Biology, 2023), 'AAPM TG Report 330: EPID-Based Quality Assurance of Linear Accelerators' (Medical Physics, 2025), and 'Comparison of Synthetic Computed Tomography Generation Methods for Magnetic Resonance Imaging-Only Definitive Pelvic Radiotherapy' (Frontiers in Oncology, 2022). He is recognized as a world leader in EPID dosimetry, having developed the first real-time patient treatment verification system using flat-panel imaging and the first remote EPID-based dosimetric auditing program. Awards include Fellowship of the Australasian College of Physical Scientists and Engineers in Medicine (2014), PULSE Early Career Medical Researcher of the Year from the Hunter Medical Research Institute (2011), the MICCAI 3D Segmentation Challenge for Clinical Applications (2009), and the Varian Prize for research in radiation dosimetry with flat-panel imaging devices (2007). His contributions influence clinical trials, quality assurance standards, and treatment efficacy worldwide.
