Dingyun Liu is a postdoctoral researcher working on wave-particle interactions (WPI) in 3D fields. She is developing the Wave Interaction Simulation Platform (WISP) using a reduced model to study the impacts of 3D fields on WPI in general geometries, with applications to energetic particles in magnetic confinement devices and radiation belt electron transport.
Prior to joining Columbia, Dingyun received her PhD from the Department of Astrophysical Sciences at Princeton University. Her thesis focused on gyrokinetic simulations of turbulence in the tokamak scrape-off layer, with close comparisons to experiments. To enable simulations in the high-collisionality regime, she implemented an implicit, moments-conserving BGK collision operator within the Gkeyll framework. She has also worked on experimental and computational studies of tokamak sawtooth crashes.
