The doctoral researcher will focus on the development of stochastic methodologies for efficient computation of kinetic systems. Kinetic interactions of particles comprise challenging problems across different fronts of modeling, computation and analysis of fluids. From hypersonic and reentry flights to the high-energy chip lithography and membranes, we rely on kinetic descriptions.

In particular, we are interested in developing Fokker-Planck based solution algorithms for efficient computation of gas flows across a wide range of rarefactions. The applications will deal with studying complex gas transport processes through mesoporous membranes, with overarching applications in gas separation and CO2 adsorption.
