RESEARCH INTERESTS
My research interests are in aqueous geochemistry and hydrogeology with an emphasis on
biogeochemical and hydrologic controls on transport and transformation in aqueous systems. I
am interested in examining scientific problems from the molecular to the field scale and my
research approach often integrates microscopic techniques with fieldwork and laboratory
experimentation and involves collaborative team efforts. I utilize numerical modeling to assist
in developing conceptual models of complex biogeochemical processes.
