I am a computational scientist in the Scientific Computing Group at the Center for Applied Scientific Computing (CASC). Prior to this, I was a postdoctoral research staff member at CASC and a post-doctoral appointee at the Mathematics & Computer Science Division, Argonne National Laboratory.

Research Interests

  • Numerical methods for hyperbolic conservation laws
  • High-resolution finite-difference and finite-volume methods
  • Non-linear, non-oscillatory compact finite-difference and finite-volume schemes
  • Multi-stage implicit and implicit-explicit (IMEX) time-integration methods
  • Scalable implementations of high-order numerical methods on massively-parallel platforms
  • Application areas: Compressible and incompressible fluid dynamics, atmospheric flows, fusion plasma dynamics
  • Current Activities and Projects

    • Development of a multifluid flow solver for interpenetrating plasmas (with applications to inertial confinement fusion)
    • High-order numerical methods for tokamak edge and other magnetically confined plasma simulations.
