I'm a staff member at Sandia National Laboratories, a US
Department of Energy lab. For many years I was in the Parallel
Computational Sciences group. In 2001, I moved to a new Computational
Biology group. In 2007, I became part of the Scalable Algorithms
group.
My work involves implementing and using scientific simulations
designed for parallel supercomputers. Often this includes the
creation of efficient parallel algorithms. The applications I work on
typically use particles, finite elements, or partial differential
equations. Some of these simulation tools are now being applied to
biology problems.
