Research Interests

My primary research focus is centered around examining groundwater-surface water interactions.  This exchange can deliver significant quantities of nutrients, trace metals, and contaminants to the coastal ocean, lakes, rivers, and wetlands.  I am interested in developing and applying techniques to resolve driving forces and mechanisms of this interaction as well as quantifying fluxes.  I am particularly interested in applying naturally-occurring radioisotopic tracers to study this exchange process in a number of unique settings, such as deep ocean settings.  Other research interests include applying natural radiotracers to a multitude of environmental processes including particle transport and atmospheric deposition.
