| Research: | Research is performed in the field of computational and theoretical fluid dynamics, in particular the modeling and numerical simulation of rheologically complex (e.g. macromolecular) fluids. Research of complex fluids involves physical modeling, experimental methods, and numerical techniques and is therefore highly interdisciplinary. My research interests span a variety of topics involved in the macroscopic and microscopic simulations of complex fluids: finite element methods, integration along fluid trajectories, finite volume methods, spectral methods, parallel computing, free surface and moving boundary problems for complex fluids, non-equilibrium thermodynamics of complex fluids, polymeric fluids containing high aspect ratio particles, integro-differential equations, stochastic differential equations. Currently, I am working on the modeling and numerical simulation of suspensions of high aspect ratio particles and the high Weissenberg number problem. |
