Media contact: Jon Bashor, +1 510 486 5849, JBashor@lbl.gov

 

 

Ann Almgren is acting group leader for the Center for Computational Sciences and Engineering and a senior scientist in the Computational Research Division at Berkeley Lab. As an applied mathematician, her areas of expertise include asymptotic analysis, numerical analysis, fluid dynamics, adaptive mesh refinement and high-performance computing for multiscale, multiphysics simulations.

Her current research interests include the design and implementation of numerical algorithms for solving partial differential equations in a variety of applications areas; core development of BoxLib, a software framework for massively parallel adaptive mesh refinement applications; low mach number models for incompressible and stratified flows; and design and implementation of MAESTRO, CASTRO and Nyx codes.
