# Shidong Jiang

My main research interests lie in the field of numerical analysis and scientific computing with particular emphasis on fast numerical algorithms and integral equation methods for solving initial/boundary value problems for various partial differential equations. I have constructed well-conditioned second kind integral equation formulations for the open-surface problems, fourth order biharmonic and modified biharmonic equations, and mode calculation of optical waveguides. I have studied sum-of-exponentials and sum-of-poles approximations and their applications to nonreflecting boundary conditions for the Schrodinger equation, the Havriliak-Negami dielectric model, the fractional derivative, layer potentials for the heat equation, and the continuous time random walk transport equation. I have also developed fast algorithms for nonlocal interactions, Brownian dynamics and molecular dynamics simulations.
