Markus Stock: All my professional career I dedicated to improve treatment outcome of radiotherapy for cancer patients by implementing new technology for high precision radiotherapy starting from stereotactic therapy as well as IMRT and personalized adaptive therapy. I was part of the team at the Medical University of Vienna who implemented for the first time VMAT for clinical treatments on Elekta machines. I also conducted a short research sabbatical at the University Medical Centre in Utrecht where I was involved in the MR-Linac project. After finishing the tenure track at the Medical University in Vienna I had the chance to build up a dual particle facility in Austria as Head of Medical Physics of MedAustron. Under my supervision and guidance MedAustron started first proton treatments in 2016 and first carbon ion treatments in 2019.
