Research interests
My mission is to develop the tools and techniques that computational scientists use to understand the world. I am particularly interested in programming models for high-performance computation for physical simulation. I also contribute to related efforts in performance portability, resilience, and numerical computing. I spend a lot of time working on the Chapel parallel programming language.
