Faculty research interests cover a broad spectrum of geotechnical and geo-environmental engineering.  Current research areas include constitutive modeling, soil-structure interaction, consolidation, behavior of shallow and deep foundations, laboratory and in-situ testing of soils, bridge approach settlement, resilient modulus, soil stabilization and soil aggregate pavement materials, dispersive and swelling clays, pore collapse in unconsolidated and poorly consolidated reservoir rocks, ground surface subsidence and mine collapse, pavement dynamics including vehicle-guideway interaction and non-destructive testing, slope stability, seepage flow through porous media, soil liquefaction, application of numerical methods to complex geotechnical engineering, rock mechanics and mining problems, static and seismic design of landfills, applications of geosynthetics in geotechnical and transportation engineering, physico-chemical behavior of soils governing the migration of pollutants through soils, centrifuge modeling and soil behavior including saturated and unsaturated soils.

Current and Recent Research Projects
