My research interests include scientific computing, parallel algorithms
and combinatorics. Much of my work has been in Combinatorial
Scientific Computing - the development, analysis and application of
discrete algorithms for applications in scientific computing.
Some of my recent (and not so recent) projects include the interplay
between graph algorithms and computer architectures, support theory - an
algebraic approach to analyzing preconditioners, the Chaco graph
partitioning tool and the related Zoltan dynamic load balancer, and a
range of algorithmic activities in scientific and high performance

I am a guest co-editor for a
special issue of SISC on Computational Science and Engineering.
I am on the editorial board for the Problems & Techniques section of
SIAM Review ,
I am also an editor of the J. Applied Numerical Analysis & Computational
Mathematics, the J. Parallel & Distributed Scientific and Engineering
Computing, the Open Applied Mathematics Journal, and the International Journal of
Computational Science and Engineering.
