Principal Member of the Technical Staff at Sandia National Laboratories. I have been involved in a wide range of projects, typically related to High Performance Computing (HPC), in the areas of Systems Management, Reliability Availability and Serviceability (RAS), Mass Storage (Hierarchical and Parallel), Light Weight Kernel development and HPC architectures. I am currently in involved in researching power issues as they pertain to HPC platforms and advanced architecuctures for next generation HPC platforms.
