I received my BS in mathematics in 1991 and my MS in computer science in 1994 from Mississippi State University. I joined Sandia National Laboratories in 1995 after serving as a graduate research assistant in the system software thrust at the MSU/NSF Engineering Research Center for Computational Field Simulation (now known as the High Performance Computing Collaboratory). While at Sandia, I`ve worked on several research and development projects associated with system software and high-performance networking for large-scale, massively parallel, distributed-memory, scientific computing systems. I`ve designed and developed high-performance implementations of the Message Passing Interface (MPI) standard on several platforms, including the Cray T3D and T3E, the Intel Paragon and TeraFLOPS (ASCI/Red), Sandia`s Computational Plant Linux clusters, and the Cray Red Storm (XT3). My research interests include high-performance, scalable communication interfaces and protocols for system area networks, operating systems for massively parallel processing machines, and parallel program performance analysis libraries and tools. I`m a Senior Member of the IEEE and the IEEE Computer Society and a Senior Member of the Association of Computing Machinery. ©
