Title: Structure-Preserving Dynamical Low-Rank Methods for Kinetic Equations of Plasmas 

Abstract: Dynamical low-rank methods have gained interest in recent years as a viable solution to the curse of dimensionality in the numerical solution of kinetic equations. Depending on the regime and nature of the solution, a direct application of these methods often results in high ranks or comes at the cost of losing physical properties such as conservation. Using the Vlasov-Fokker- Planck equation as a model problem, which is the governing equation for plasma dynamics, we demonstrate that when tuned to the problem’s structure, the dynamical low-rank method can provide an efficient and robust approximation compared to the full tensor method. This talk is based on the joint work with Jack Coughlin and Uri Shumlak. 

Bio: Jingwei Hu is a Professor in the Department of Applied Mathematics at the University of Washington. She also holds an adjunct professorship in the William E. Boeing Department of Aeronautics & Astronautics. Dr. Hu earned her Ph.D. from the University of Wisconsin-Madison in 2011 and was a postdoctoral fellow at the University of Texas at Austin from 2011 to 2014. Prior to joining UW in 2021, she held positions as an Assistant and later as an Associate Professor at Purdue University. Her primary research interests focus on numerical analysis and scientific computing, particularly the development of efficient and structure-preserving numerical methods for multiscale kinetic equations across various science and engineering applications. Dr. Hu received the NSF CAREER award in 2017 and was a plenary speaker at the Canadian Applied and Industrial Mathematics Society (CAIMS) Annual Meeting in 2022. She currently serves on the editorial boards of several mathematical journals, including La Matematica, the official journal of the Association for Women in Mathematics (AWM), and the SIAM Journal on Applied Mathematics.
