Molecular biomarkers are building blocks or degradation products of organic matter that accumulate all over Earth in living cells, sediments, particulate organic matter, and dissolved organic matter (DOM).  Because biomarkers are associated with specific organisms or evolutionary lineages, this approach has provided unequivocal evidence of the biogeochemical reactions and metabolisms performed by mixed communities and uncultured microorganisms.  The goal of my research is to identify and quantify globally important biogeochemical fluxes by deciphering the chemical information imparted to bi
