Ralph Kube

Ralph Kube joined the Princeton Plasma Physics Laboratory as a research physicist in 2019 and is a member of the US SciDAC Center for High-Fidelity Boundary Plasma Simulations (HBPS), led by Principal Investigator Choong-Seock Chang. His research interest lies in understanding the edge and scrape-off layer regions of magnetically confined plasmas. Ralph's current work includes applying machine learning methods to accelerate the full-f gyrokinetic particle-in-cell code XGC1. He also develops novel workflow tools tailored to automatically analyze big and fast data streams produced by fusion experiments and high-fidelity numerical simulations.

Ralph graduated with a B.Sc. in Physics from RWTH Aachen University in 2004. He received a M.Sc. and a PhD in Plasma Physics from UiT The Arctic University of Norway. After that he worked as a postdoctoral research fellow at the University of Innsbruck in Austria and at UiT in Norway where he investigated the statistical properties of intermittent fluctuations observed in scrape-off layer plasmas.
