The Paul Scherrer Institute (PSI), Switzerland's largest research institute for natural and engineering sciences, invites applications for a PhD Student in Proton Therapy Research. PSI is renowned for its cutting-edge research in future technologies, energy, climate, health innovation, and the fundamentals of nature. The Center for Proton Therapy at PSI has been a global leader in treating cancer patients with protons since 1984, pioneering innovative radiotherapy modalities.

This PhD project focuses on advancing personalized cancer treatment by developing a mathematical framework to predict the biological effects of proton therapy compared to conventional radiotherapy. The research will emphasize nano-dosimetric quantities, which directly represent DNA cell damage, as a novel approach to assess the biological effectiveness of proton therapy. The successful candidate will optimize proton therapy treatments by integrating these parameters and investigate the impact of various treatment delivery modalities.

The position is part of a collaborative project involving the University of Zurich and the Cyclotron Centre Bronowice in Krakow. The selected PhD student will be registered at ETH Zurich, benefiting from a vibrant, interdisciplinary research environment and systematic on-the-job training. PSI offers modern employment conditions, personal development opportunities, and support for work-life balance.

Applicants should possess a Master’s degree in physics, mathematics, engineering, or related natural sciences, and demonstrate fluency in English. A strong interest in proton therapy research, mathematical modelling, and programming is essential. The position is fully funded, with a full-time contract and access to PSI’s extensive resources and training culture.

Applications must be submitted online by 15 March 2026, including referee contact details. For further information, candidates may contact Prof. Dr Antony John Lomax. For more details and to apply, visit the official PSI application portal.
