  • Computational Physics — I have extensive experience developing and implementing methods for compressible hydrodynamics, radiation transport, and their coupling in a wide range of regimes.  I also have expertise in running, analyzing, and extracting scientific insights from large multi-physics simulations.
  • High Performance Computing — I have designed and implemented multi-physics software that shows nearly ideal strong scaling on well over one hundred thousand processor cores.
  • Astrophysics — I have expertise in a range of problems in astrophysics, particularly black hole accretion and core-collapse supernovae.  Both involve complex radiating turbulent flows, each with their own additional physics.
