Dr Scott Penfold - Lead Medical Physicist

Dr Scott Penfold is the Lead Medical Physicist at the Australian Bragg Centre for Proton Therapy and Research (ABCPTR). He is an Affiliate Senior Lecturer with the Department of Physics at the University of Adelaide. He previously worked as a medical physicist with the Radiation Oncology Department at the Royal Adelaide Hospital.

Scott first started working in the field of proton therapy during his PhD studies at the University of Wollongong in 2007. The project investigated image reconstruction methods in proton computed tomography. During his PhD, Scott was supported by a Cancer Institute NSW Research Scholars Award to spend time at Loma Linda University Medical Centre, the site of the world’s first hospital-based proton therapy system. Since then Scott has continued to work with collaborators to undertake research in proton therapy, having published 18 peer-reviewed journal articles in the field.

Following the announcement of Federal Funding to support the Australian Bragg Centre project, Scott instigated the Particle Therapy Working Group (PTWG) within the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM). Scott continues to Chair the group and work closely with members distributed throughout Australia.

Scott has led the radiation safety assessment of the ABCPTR and worked closely with the Clinical Reference Group in end-user design aspects.

Scott’s ultimate objective is to use physics to improve the patient experience in radiotherapy, be it through more precise delivery, shorter treatment courses or improving access by reducing costs.

In 1986, he completed his Bachelor of Medicine, Bachelor of Surgery (MBBS) at the University of Adelaide and in 1995 became a fellow of the Royal Australian and New Zealand College of Radiologists (RANZCR). He completed specialist oncology training in Brisbane, Queensland prior to becoming a founder of the North Queensland Oncology service in Townsville.

In 1996, Michael returned to Adelaide as a consultant radiation oncologist and completed his MBA at the University of Adelaide, receiving the honour of mace-bearer as the highest candidate of the professions. With an active interest in the provision of radiation oncology services in rural and remote areas, Michael established Darwin’s Alan Walker Cancer Care Centre (AWCCC) in 2010 and remains its Director. In addition to his role at Icon and AWCCC, Michael is the Director of Radiation Oncology at the Royal Adelaide Hospital and Lyell McEwin Hospital.

Throughout his career, Michael has maintained an active interest in research, quality improvement and governance, holding key positions including with the Government and Regulatory Affairs Committee from 2003 until 2010 and as a RANZCR Faculty Board member between 2006 and 2011. He is currently a member of the RANZCR Particle Therapy Group and several other leading cancer trial groups including the American Society of Radiation Oncology (ASTRO), the European Society for Radiotherapy and Oncology (ESTRO) and the Trans Tasman Oncology Group (TROG).  In 2014, Michael was awarded the Best of ASTRO (USA) and Trial Excellence Award (TROG) for his work on a palliative oesophageal trial evaluating the efficacy of radiation therapy versus combined therapy treatment to decrease swallowing complications experienced by advanced oesophageal cancer patients.

Michael sits on the Board of the Asia-Oceania Particle Therapy Co-Operative Group (PTCOG-AO). He is involved in a number of Australian and international research projects with a focus on planning and developing new radiation therapy facilities and improving Indigenous cancer care and quality of life during cancer treatment. Michael’s clinical experience covers a broad range of solid tumour malignancies with special interest in breast cancer, head and neck cancer, upper gastrointestinal cancer, colorectal cancer and skin cancers.

In January 2021, Michael was appointed a Member of the Order of Australia (AM) for his significant service to medicine, and to radiation oncology.
