Research

Many problems arising in science, engineering, and technology share the common need to deal with phenomena interacting on a wide range of scales. Under the instruction of Professor Shlomo Ta'asan , my thesis work has been focused on developing coarse-graining methodologies to understand how physical principles or models in a given discipline change across scales. We have studied coarse-graining methods for two major problems: (1) the passage from Molecular Dynamics (MD) models of fluids to the Navier-Stokes equations, and (2) modeling and simulation of grain growth in polycrystalline materials at different scales.
