I'm a staff member at Sandia National Laboratories, a US
Department of Energy lab, in the Center for Computing
Research. I'm currently in the Multiscale Science department.
Previously I've been in the Scalable Algorithms, Computational
Biology, and Parallel Computational Sciences departments.
My research involves implementing and using scientific simulations
designed for parallel supercomputers, which often requires creation of
efficient parallel algorithms. Many of the models are particle based,
some use structured grids or finite elements. Most of the codes I
develop are for materials modeling, some for biology and informatics
problems.
