PhD, Earth Sciences (Hydrogeology), University of Waterloo – 1991

My main research interests are understanding and integrating the basic processes which control the fate and transport of contaminants in the environment, particularly in groundwater. Our current understanding of these processes, or lack thereof, limits our ability to predict natural fate and to plan and conduct appropriate remediation of contaminated sites. My current research has to do with transport and/or transformation of organic contaminants, including chlorinated solvents, or nutrients and dissolved organic matter.
