I received my Ph.D. in Civil Engineering, from U.C. Berkeley in 1998 and am a former student and postdoc with Jim Demmel in the Computer Science Division, at U.C. Berkeley. I work in the Scalable Solvers Group at Lawrence Berkeley National Laboratory, and as an adjunct research scientist in the Applied Physics and Applied Mathematics Department at Columbia University.
My research interests are in large scale simulations, extreme-scale multigrid equation solvers, adaptive mesh methods, and particle in cell methods for plasma physics applications.
I work as a developer in the PETSc numerical library - developing its algebraic multigrid (AMG) framework the advance Structure Preserving, Adaptive Discretizations for Extreme-scale Solver (SPADES) infrastructure in PETSc. I work with computational physicists at Princeton Plasma Physics Laboratory (PPPL) on kinetic and fluid models for magnetically confined fusion plasmas.
