### Parallel Linear Algebra

Linear algebra calculations are at the core of most scientific computations. For this reason, efficient parallel algorithms for linear algebra operations are critical to the effective use of parallel machines. I have worked on the parallelization of direct linear- and eigen-solvers as well iterative methods. In addition, I have worked on parallel algorithms for a variety of scientific computing problems which don't involve linear algebra as described here .
