  Current research & teaching focus

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

Presently teaching the graduate level and upper undergraduate level Computational Fluid Mechanics (AEM 5251) in the Autumn 2011 & 2012 semesters.

Currently, I am a contributor to the baseline computational tool used by Prof. Candler's group members and collaborators. I am authoring the next generation massively parallel DSMC solver for Prof. Schwartzentruber's group (to be completed in late 2012). Also continuing the 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.
