Tony Lomax obtained his bachelor degree at Brighton Polytechnic, followed by an MSc and PhD in Medical Physics from the University of Aberdeen. He subsequently worked for 2 years as a medical physicist in the National Health Service, before moving to Switzerland in 1992 to work in the Center for Proton Therapy at the Paul Scherrer Institute. In 2001 he became head of the Medical Physics group for the proton therapy project there. His main research interests lie in the development of intensity modulated proton therapy, problems of robustness and uncertainty in treatment delivery and adaptive proton therapy. Since April 2005, he has been a faculty member of the Physics Department at ETH (Swiss Federal Institute of Technology), Zurich and is currently joint director of the Master of Advanced Studies in Medical Physics and the medical physics track of the Bio-Medical Engineering Master’s program at the same institute. In 2007 he was made Titular Professor in the Physics Department at ETH. From 2010-2014, he was on the editorial board of ‘Physics in Medicine and Biology’ and remains on the international advisory board. He is a regular member of the scientific committees for ASTRO, ESTRO, AAPM and the ICCR and from 2015 – 2023 was the physics co-chair of the PTCOG Scientific Program Sub-committee. In 2023 he became an honorary member of the Swiss Association of Scientific Radiation Oncology (SASRIO) and in 2024 was the recipient of the Robert Wilson Award for his achievements in particle therapy from the Particle Therapy Cooperative Group (PTCOG). He is the author or co-author of over 300 peer reviewed papers, 13 book chapters and more than 500 invited and proffered conference presentations.
