Research Summary:

My research focuses on the carbon, nitrogen, and phosphorous cycles in aquatic environments, from wetlands to the open ocean. Experimental approaches are used to characterize biogeochemical processes and the roles of microorganisms as key players in the production and transformation of organic matter. Geochemical approaches are used to integrate processes over space and time.
