Professional Background

Ben Zhu is a theoretical and computational physicist with general interests in fusion and laboratory plasmas. He received his BS degree in applied physics from the University of Science and Technology of China (2008), his MS degree in applied science from the University of California, Davis (2009), and a PhD in physics from Dartmouth College (2017). His PhD dissertation investigated the interaction between turbulence, transport, and spontaneously generated shear flow at the tokamak edge region using a global 3D two-fluid numerical model. He worked as a research associate at Dartmouth College before joining LLNL in 2018.

Research Interests

Current research topics include fluid and kinetic theories; basic plasma instabilities; turbulence, transport, and disruption processes in the magnetic confined fusion devices; machine learning applications in plasma physics; and high performance computing.
