Matthias Hoelzl is currently serving as an ITER Scientist Fellow on Disruption and Runaway Electron Mitigation Theory and Simulation at the ITER Organization, a position held since September 2023. In addition, Matthias has been with Max-Planck-Institut für Plasmaphysik since March 2010, where responsibilities include Group Leader for non-linear MHD and Senior Researcher, focusing on the development and application of non-linear MHD codes for large-scale instabilities in tokamak plasmas, alongside supervising PhD students and Postdocs. Previously, Matthias worked as a Postdoctoral Researcher, contributing to the development of non-linear MHD codes and their coupling to a resistive wall model. Academic qualifications include a Dr. rer. nat. in Physics and a Master's degree in Physics, both from the Technical University of Munich, attained in 2010 and 2006 respectively.
