I am interested in mathematically modeling
porous media - any material consisting of a solid and one
or more other phases. In particular I enjoy modeling swelling porous
materials (materials that swell due to the addition of more material, changing
the concentration of ions, or the unloading of a pressure load), and
porous materials with more than
one fluid phase. Examples of swelling porous
media include clays (expansive soils), polymers
(such as drug-delivery polymers and bio-polymers), and cell membranes.
To develop models I use
a combination of averaging theory and thermodynamics (exploitation of the second law
and manipulating independent variables to relate theory with what is measurable).
PhD students have worked on modeling drug-delivery systems involving swelling
polymers such as Aleve
( Tessa Weinstein and Keith Wojciechowski),
the movement of cilia in lungs (Kannanut Chamsri), and transport of water through
multiphase fluid porous media
( Eric Sullivan).
I have also contributed in collaborative settings to modeling forest fires,
upscaled reactive transport, laminar to turbulent transition of fluid
flow, and refugee movement.
