Overview

Tianshi Lu is an Associate Professor of Mathematics. After obtaining his Ph.D. in Applied Mathematics at SUNY at Stony Brook in 2005, he worked as a Research Associate and an Assistant Computational Scientist on computational fluid dynamics at Brookhaven National Laboratory. He joined 麻豆破解版 State University in 2008 with promotion to Associate Professor in 2012.

Tianshi Lu's research ranges from numerical analysis to computational physics and statistics. He specializes in multiphase computational fluid dynamics and magnetohydrodynamics simulations, free surface flows, numerical schemes for advection-dominated systems, as well as computational quantum optics, spectral functions and Zeta functions on manifolds, and random fields on randoms. His current research involves modeling and simulation of multiphase flows in additive manufacturing, superconvergence of discontinuous Galerkin methods for hyperbolic conservation laws, and vector random fields on homogeneous spaces.
