Our focus is on systems that are complex due to rheological properties of the considered fluids, complicated flow geometry, complex multiphysics aspects of the forces governing the flows, or a combination of these factors. We carry out modeling and simulations of such problems, as well as developing appropriate computational methods. In some cases, we also carry out physical experiments in our Undergraduate Capstone Laboratory in coordination with the Capstone Course taken by our applied mathematics majors. Our work is carried out in collaboration with mathematicians and scientists from a number of different institutions (listed on our Research pages).

Our research is supported by the Center for Applied Mathematics and Statistics, the Department of Mathematical Sciences, and by grants from a number of federal research agencies.
