Ulrike Meier Yang, LLNL Dr. Ulrike Meier Yang is the Mathematical Algorithms & Computing group lead in the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory. She leads the xSDK (extreme-scale scientific software kit) project in the US Department of Energy’s Exascale Computing Project. Her research interests are numerical algorithms, particularly iterative linear system solvers and algebraic multigrid methods, parallel computing, performance evaluation and scientific software design. She has contributed significantly to the hypre software library, which received an R&D 100 award in 2007. She is currently an associate editor for the SIAM Journal on Matrix Analysis and Applications and the Journal of Parallel and Distributed Computing. Prior to joining LLNL in 1998, she worked in the Center for Supercomputing Research and Development at the University of Illinois at Urbana-Champaign (1985-1995) and in the Central Institute of Applied Mathematics at the Research Centre Juelich at Juelich, Germany (1983-1985). She earned her Ph.D. in Computer Science at the University of Illinois at Urbana-Champaign in 1995 and a Diploma in mathematics at the Ruhr-University Bochum, Germany, in 1983.
