Yichen Fu is a postdoctoral researcher at the Columbia Fusion Research Center, where he works with Prof. Ben Zhu. His research focuses on applying analytical and computational tools to study plasmas at the boundary of magnetic fusion devices, including tokamak edge transport and turbulence.
Yichen received his Ph.D. in plasma physics from the Department of Astrophysical Sciences at Princeton University. His doctoral research focused on plasma waves, using topological and geometrical methods adapted from condensed matter theory. He also worked on structure-preserving numerical algorithms for collision operators and machine-learning-based prediction of tokamak disruptions.
Before joining Columbia, Yichen was a postdoctoral researcher in the Fusion Energy Science group at Lawrence Livermore National Laboratory (LLNL). There, he studied tokamak boundary transport using the UEDGE code and developed statistical methods to infer cross-field transport coefficients, together with their uncertainties, from experimental data.
