Honors and awards
He is the 2021 recipient of the John von Neumann Lecture Prize, the highest honor and flagship lecture of Society for Industrial and Applied Mathematics (SIAM). The prize recognizes his fundamental contributions to the numerical solution of partial differential equations: "His work on finite difference essentially non-oscillatory (ENO) methods, weighted ENO (WENO) methods, finite element discontinuous Galerkin methods, and spectral methods has had a major impact on scientific computing."[3]
The Association for Women in Mathematics has included him in the 2020 class of AWM Fellows for "his exceptional dedication and contribution to mentoring, supporting, and advancing women in the mathematical sciences; for his incredible role in supervising many women Ph.D.s, bringing them into the world of research to which he has made fundamental contributions, and nurturing their professional success".[4]
