Research Interests: Application of volume averaged continuum theory for multiphase systems.  The continuum theory provides the same organizational advantages as are available for single-phase systems.  Current research interests include fluid/solid separations and flows through porous media.  Specific applications include cake filtration, depth filtration, cross-flow filtration, electrorheological fluid flow through packed beds, and droplet coalescence in fibrous filters. Other areas of interest include nanofibers, high temperature fibers, fiber orientation in filter media, non-Newtonian flows in porous media, and catalytic reduction of NOx and CO gases.
