The focus of my research is on large-scale instabilities in tokamak plasmas. Simulations in particular with the non-linear MHD code JOREK aim to interpret and predict fusion plasma experiments. The emphasis lies on edge localized modes (ELMs) and their interaction with resonant magnetic perturbation (RMP) fields and pellets as well as disruptions including mitigation via massive gas injection (MGI), vertical displacement events (VDEs) and conducting wall effects.
