Joost Verhoeff MD PhD is Professor and Head of the Department of Radiation Oncology at Amsterdam UMC—one of Europe’s largest radiotherapy centers where he leads a multidisciplinary team advancing precision cancer care. He also serves on the executive board of Cancer Center Amsterdam, the Supervisory Board of Radiotherapiegroep, and he chairs the Radiation Oncology Science Council (ROSC) of the EORTC.

His clinical and research work focuses on brain tumors, lung cancer, and cardiac arrhythmias (STOPSTORM.eu), leveraging high-precision radiotherapy and MR-Linac innovation to deliver personalized, quality-of-life-centered treatments.

Professor Verhoeff’s leadership in redefining radiotherapy standards aligns closely with TROG 2026’s theme, “Driving Intelligent Trials”, particularly the Precision & Performance sub-theme on AI-enabled and efficient trial designs. His EORTC collaborations underscore the importance of international synergy—fittingly resonating with the new TROG–EORTC MOU and the shared ambition to co-develop smarter, globally connected clinical research.
