Current Research:

Particulate and multiphase systems are encountered in many natural, biological, and industrial processes. Their behavior is governed by physics at multiple length scales – from molecular, to typical dimension characterizing the individual phase boundary, to macroscale on which the microstructure is changing. Understanding of these systems in general can be improved through use of numerical simulations of appropriate phenomena at various lengthscales, theories for multiscale modeling, and experiments. Our research focuses on development of efficient algorithms for numerical simulations and theory. We apply these to variety of multiphase problems, and compare the predictions with experiments carried out either by our collaborators or available in the literature.
