Areas of Knowledge

• Extensive experience in numerical methods, especially in the numerical solution of ordinary differential equations and coupled systems of partial differential equations.
• Extensive physical modeling experience, primarily in
  • radiation transport, radiation hydrodynamics, neutronics, diffusion and magnetohydrodynamics (spherical harmonics (P_N) and simplified spherical harmonics (SP_N) methods, discrete ordinates (S_N), Monte Carlo techniques), and
  • fluid dynamics (multi-phase, multi-component flow; surface tension modeling; heat and mass transfer; kinetic evaporation-condensation models; rarefied gas dynamics; melt front propagation models).
• Experience with linear algebra (Conjugate Gradient and other Krylov methods, algebraic multigrid), regression (curve-fitting), root-finding, optimization and other various numerical techniques.
• Extensive experience with modern massively parallel computing systems, in particular with the Unix/Linux operating system (including system administration), various computer languages (Fortran95, m4, L^ATEX and friends, scripting languages, Makefiles, elisp, awk, HTML, perl), and various architectures (Current: Intel/Linux, Compaq/Linux, Compaq/Tru64Unix, Apple/Darwin, SGI/IRIX; Historical: Sun, Cray, HP, Thinking Machines, Vax).
