Ann S. Almgren is an American applied mathematician who works as a senior scientist and group leader of the Center for Computational Sciences and Engineering at the Lawrence Berkeley National Laboratory. Her primary research interests are in computational algorithms for solving PDE's for fluid dynamics in a variety of application areas. Her current projects include the development and implementation of new multiphysics algorithms in high-resolution adaptive mesh codes that are designed for the
latest multicore architectures.[1]
In 2015 she became a fellow of the Society for Industrial and Applied Mathematics "for contributions to the development of numerical methods for fluid dynamics and applying them to large-scale scientific and engineering problems."[5] She also serves on the editorial boards of SIREV[6] and CAMCoS[7]
