Steve Hammond is director of the Computational Science Center at the National Renewable Energy Laboratory (NREL). He is responsible for developing and leading NREL's laboratory-wide efforts in computational science. He initiates and oversees innovative research programs in computational science, mathematics, and scientific computing in support of NREL's Department of Energy (DOE)-based mission. This includes leading NREL's efforts in energy efficient data centers.

Prior to NREL, Steve managed the Computational Sciences section at the National Center for Atmospheric Research (NCAR). He led staff conducting research and development in areas such as computational fluid dynamics and parallel communications algorithms for parallel architectures. Steve was technical lead on the DOE-funded effort to develop the first massively parallel version of NCAR's community climate model, CCM2, originally developed for vector systems.
