The cycling of the element carbon is fundamentally important to the functioning of our planet. My research has focused on the biogeochemical transformations of carbon with an emphasis on process-oriented studies of the evolution and fate of organic matter in surficial environments. Methanogenesis, methane oxidation, and the influence of macrofauna on organic carbon turnover are some of the processes that have been investigated in field areas ranging from the North Carolina slope to the Amazon shelf.

Delineating the transformations of carbon from source (mountains) to sink (marine sediments) in small watershed systems ranging from Northern California to Papua New Guinea and New Zealand is a recent focus of research. Understanding what controls the persistence and/or breakdown of organic species in the environment is the major impetus for this work.
