I have moved to Texas Tech and have a new web page
Kevin works in the
Computational Sciences and Mathematics Research department at Sandia Livermore.
He does research on numerical algorithms and also on new ways of thinking about
software for scientific computing.
His algorithmic
research interests include PDE-constrained optimization, level-set methods
for topology optimization, methods for decision-making under uncertainty, and
symmetry-preserving discretizations for PDEs.
His software research interests include automatic differentiation, modeling
languages for parallel scientific computing, and software interoperability.
In an earlier life Kevin did research
in theoretical and computational
astrophysics, primarily on the dynamical evolution of galaxies and star clusters
which in turn involved -- you guessed it -- PDE simulations, optimization,
symmetry-preserving discretizations, and software
development. At one time, Kevin also knew a little bit about nonlinear dynamics
and statistical physics, but he has not done any recent work in those areas.
Kevin is one half of a successful solution of the professional two-body problem.
The other (better) half is found here.
Some pretty pictures
Some codes
- Kevin is the designer and principal developer of
Sundance,
which is a system for highly efficient (in human time)
development of highly efficient (in CPU time)
parallel PDE simulation and optimization codes.
- Kevin also contributes to the
Trilinos system of parallel
solver components.
