Associate Professor
Benedikt Geiger is an Associate Professor at the University of Wisconsin–Madison College of Engineering, affiliated with the Department of Nuclear Engineering and Engineering Physics and Electrical & Computer Engineering. He leads the Helically Symmetric eXperiment (HSX), focusing on quasi-symmetry and transport in stellarators, and directs the Turbulence and Spectroscopy Group conducting diagnostics at DIII-D, W7-X, and NSTX-U. Ph.D., Ludwig-Maximilians University (2013) Diploma (MS), Ludwig-Maximilians University (2009) Diploma Thesis, Max-Planck Institute for Physics (2009) His research spans experimental plasma spectroscopy, particle/heat transport, synthetic diagnostics, and turbulence analysis in fusion devices. Recent work includes developing deep learning algorithms for ELM prediction and real-time confinement regime detection, alongside turbulence studies in negative triangularity plasmas and impurity transport in W7-X. Key awards include the 2025 Grainger Institute for Engineering Professorship, 2020 DOE Early Career Award, 2014 Landau Spitzer Award, and the 2014 Otto-Hahn Medal. He holds leadership roles in the National Stellarator Coordinating Committee, Transport Task Force, and International Stellarator and Heliotron Workshop.
