Research Biography
Professor Wallace's research involves the mechanics of fluids in porous media. Current research focuses on contaminated transport and remediation in groundwater systems including the role of nonaqueous phase liquids such as gasoline. This includes experimental and numerical investigation of the processes which control in situ remediation in unsaturated and saturated soils. Methods under study include forced venting, air sparging, the use of organomodified soils for sorption zones.
