Nils Leuthold became a member of the Columbia Applied Physics and Applied Mathematics Department in 2022. He is currently located off-site at General Atomics (San Diego) studying Edge-Localized Modes (ELMs) in tokamaks. His studies focus on the mechanism behind ELM suppression via the application of resonant magnetic perturbation (RMP) fields as well as establishing an ELM-suppressed scenario in hydrogen and helium plasmas at DIII-D (General Atomics, USA) and ASDEX Upgrade (Max Planck Institute for Plasma Physics, Germany). This work is in preparation for the ITER pre-fusion power operation phase planned to start in 2028. Nils obtained his Ph.D. at the Ludwig Maximilian University of Munich in collaboration with the Max Planck Institute for Plasma Physics in 2020. The topic of his thesis was the increase of particle transport triggered by RMPs in the ASDEX Upgrade tokamak.
