    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).
