 My research focuses on the carbon, nitrogen, and phosphorous cycles in aquatic environments. Experimental approaches are used to characterize biogeochemical processes and the roles of microorganisms as key players in the transformations of C, N and P, and geochemical approaches are used to integrate processes over space and time.
