David Thwaites

Professor David Thwaites serves as Professor of Medical Physics in the School of Physics at the University of Sydney, affiliated with the Institute of Medical Physics. His academic interests center on radiation oncology physics, including radiation dosimetry, ionizing radiation, radiation protection, Monte Carlo simulations, and quality assurance in radiotherapy. Thwaites has directed the Institute of Medical Physics and contributed extensively to advancements in clinical linear accelerators, kilovoltage x-ray beam dosimetry, and small-field detectors for stereotactic radiotherapy. His research addresses accuracy in radiotherapy dosimetry, evaluating modern technologies and techniques for improved precision and safety in treatment planning and delivery.

Thwaites has authored or co-authored numerous influential publications. Key works include 'Back to the future: the history and development of the clinical linear accelerator' (2006, Physics in Medicine & Biology), 'Advances in kilovoltage x-ray beam dosimetry' (2014, Physics in Medicine and Biology), 'Radiotherapy physics in practice' (2000), 'Assessment of new small-field detectors against standard-field detectors for practical stereotactic beam data acquisition' (1999, Physics in Medicine & Biology), and 'Accuracy required and achievable in radiotherapy dosimetry: have modern technology and techniques changed our views?' (2013, Journal of Physics: Conference Series). Earlier contributions encompass 'Quality assurance in radiotherapy: European Society for Therapeutic Radiology and Oncology advisory report' (1995, Radiotherapy and Oncology) and 'Bragg's rule of stopping power additivity: A compilation and summary of results' (1983, Radiation Research). His scholarship has garnered thousands of citations, impacting global standards in medical physics and radiotherapy practices through involvement in international conferences such as the International Conference on 3D Radiation Dosimetry.
