Ed D'Azevedo  
Ed D'Azevedo is a staff scientist in the Computational Mathematics Group at the Oak Ridge National Laboratory. He obtained his B. Math in 1983, M. Math in 1985, and PhD. in 1989 all from the Department of Computer Science in the Faculty of Mathematics at the University of Waterloo, Ontario, Canada. D'Azevedo's current research interests include developing highly scalable parallel solvers that can take advantage of acceleration on Graphics Processor Unit and in enhancing the parallel efficiency of scientific applications running on leadership supercomputers. D'Azevedo has contributed to several projects in materials science and fusion in the Scientific Discovery through Advanced Computing (SciDAC) program. He has developed the on outofcore and compact storage extensions for the ScaLAPACK library and has made fundamental contributions in optimal mesh generation.  
Cory Hauck  
Cory Hauck has a Ph.D in applied mathematics from the University of Maryland. Dr. Hauck is interested in computational aspects of kinetic theory and hyperbolic balance laws, including moment methods, asymptotic analysis, and numerical schemes for multiscale problems.  
Kody Law  
Kody Law is a staff Mathematician in the Division of Computer Science and Mathematics at Oak Ridge National Laboratory.
