Dr. Wenxiao Pan is a scientist in the Computational Science and Mathematics Division at the Pacific Northwest National Laboratory.

Dr. Pan's research interest covers diverse topics in computational mathematics both on algorithms and applications. The major focus addresses fields in multiscale/multiphase/multiphysics modeling, the corresponding numerical methods, and parallel large-scale simulations of complex systems. Specific areas include reduced order modeling, stochastic multiscale modeling, coarse-grained molecular simulations, and their applications in biophysics, geophysics, chemical engineering and materials.
