Research

My research program focuses on modeling and measurement of mass and energy transport and distribution in porous media. Specific research interests include: (1) hydraulic behavior of swelling soils and liner materials; (2) interfacial pore scale phenomena affecting liquid organization and behavior in porous media; (3) preferential flow in structured soils and fractured rock; (4) liquid behavior in porous media under reduced gravity for space exploration; (5) stability and flow of fine granular materials; (6) application of X-ray Computed Tomography (CT) for quantification of pore topological attributes. I am also interested in application and development of cutting-edge measurement techniques for in situ characterization of soil hydraulic properties.
