Research Statement

My research is focused on the simulation of engineering problems that would be difficult to address experimentally.   Specifically, I'm interested in multiphysics problems that involve Computational Fluid Dynamics, fluid structure interactions, thermochemistry and high performance computing.  The tools that I have helped develop can solve partial differential equations on massively parallel computing platforms.   Examples of recent simulation scenarios include, flow over solar panel arrays, flow through deforming mitrial valves and the transport of airborne viruses in classroom settings.
