Research Interests: High performance computational fluid dynamics (HPC, CFD) for
compressible and incompressible, hydrodynamic and magnetohydrodynamic
turbulent flows. The use of subgrid modeling (regularizations, LES) to
extend the range of physical parameters probed by large, parallel
simulations (especially for flows with strong, impulsive events) as
well as new models and smoothness properties (computability).
