My research focuses on characterizing complicated hydrogeology in fracture, karstic or contaminated sites.  I utilize physical hydrogeologic methods and electrical geophysical techniques to solve fluid flow and transport problems.

Research Program
Current research projects include evaluation of discharge mechanisms in the Great Artesian Basin, South Australia, and NAPL evaluation projects across the U.S.
