John N. Shadid

John Shadid is a Distinguished Member of the Technical Staff at Sandia National Laboratories in the Computational Science R&D Group. John received a BS and MS degree in Mechanical Engineering and a M.S. degree in Mathematics from the University of Wisconsin-Milwaukee. He received his Ph.D. in Mechanical Engineering from the University of Minnesota in 1989. His thesis work included both experimental and computational studies of the hydrodynamic stability of thermal-convection driven fluid flows. After graduation John joined Sandia National Laboratories as a Senior Member of the Technical Staff in the Parallel Computational Sciences Department and in 1999 became a Distinguished Member of the Technical Staff.

John has contributed in the areas of analysis, numerical methods, algorithm development and software development of solution methods for coupled nonlinear PDE systems. At Sandia John has been lead PI and Co-PI on a number of large-scale computational science projects. These projects include research and development of a parallel implicit transport/reaction simulation code, MPSalsa, and a parallel preconditioned Krylov solver library, Aztec. The Aztec library received a R&D100 award in 1997. The MPSalsa simulation code has been honored twice as a Gordon Bell Prize finalist. John's current research interests include: High performance computing, parallel algorithm development, numerical solution methods for multiple-time-scale non-linear coupled PDEs, spatial discretization methods for PDEs, and the simulation of a wide range of complex transport/reaction systems that includes most recently MHD systems.
