Yang Liu is a postdoctoral fellow in the Scalable Solvers Group of the Computational Research Division at Lawrence Berkeley National Laboratory, in Berkeley, California. Dr. Liu received the Ph.D. degree in electrical engineering from the University of Michigan in 2015. From 2015 to 2017, he worked as a postdoctoral fellow at the Radiation Laboratory, University of Michigan. His main research interest is in computational electromagnetics (including fast time-domain integral equation solvers, fast direct integral and differential equation solvers, and multi-physics modeling), numerical linear and multi-linear algebras (including sparse solvers, randomized low-rank, butterfly and tensor algebras), and high-performance scientific computing. Dr. Liu authored and co-authored the Sergei A. Schelkunoff Transactions Prize Paper, APS 2018, second place student paper, ACES 2012, and the first place student paper, FEM 2014.
