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.
