Research interests:

Design and optimization of algorithms on parallel machines
High performance algebraic solvers
Sparse matrix computations
Mathematical software

I do research and provide support for mathematical software on the parallel machines at NERSC. Currently, I am heavily involved in the DOE SciDAC projects. Previously I worked on NSF NPACI project.
I received Ph.D. in Computer Science from UC Berkeley.
