Presently, I am working on advancing numerical methods for continuum simulations, particle-based and hybrid methods in aerothermodynamics with professors G.V. Candler and T. Schwartzentruber. The research focus is in hypersonics, aerothermodynamics, advanced simulation of hypersonic flows, ablation, numerical methods, chemical kinetics and computational physics.

I am part of a project led by professors D.Gebre-Egziabher, E.Longmire, J.Mueller, and G.V. Candler to develop HyCUBE (the Hypersonic Configurable-Unit Ballastic Experiment), a concept platform for performing a multitude of experimental measurements during hypersonic re-entry using miniature spacecraft.

Previously, I taught the graduate level and upper undergraduate level Computational Fluid Mechanics (AEM 5251) in the Autumn 2011 & 2012 semesters.

After having architected the prototype, I am presently a contributor to the baseline computational tool used by prof. Candler's group members and collaborators, US3D. The software is presently maintained by Dr. Heath Johnson and has been commercially available through the Univ. of Minnesota's Office of Technology Commercialization (OTC). I have authored and I am presently maintaining the next generation massively parallel DSMC solver for prof. Schwartzentruber's group (MGDS v2). I am continuing a decades-long collaboration with Dr. Matt MacLean & Dr. Michael Holden of CUBRC in a joint experimental and computational program for code validation. I am a participant of the NATO RTO AVT activities on computational tools/methods readiness assesements and a reviewer of several journals in aeronautics & computational sciences.
