I am a staff scientist in the Scalable Solvers Group of the Applied Mathematics and Computational Research Division at Lawrence Berkeley National Laboratory (LBNL). My broad research interests lie in the development of fast and parallel scientific computing tools for exascale applications. My researh topics include matrix and tensor algorithms for dense and sparse linear systems, randomized algorithms, highly oscillatory problems, high-dimensional PDEs, communication avoiding algorithms, uncertainty quantification and autotuning, scientific machine learning, multi-resolution algorithms, multi-physics and multi-scale modeling. My application interests span electromagnetics, seismic inversion, accelerator physics, fusion simulation, quantum chemistry, nuclear physics, X-ray tomography, optical computing, and quantum computing, etc.
