Life on our planet is constrained within bounds set by the transport and transformations of the elements. Carbon cycling in particular plays a central role in Biogeochemistry on a range of scales in time and space.My research addresses what happens after deposition of organic matter in sediment, and as it turns out, what happens is … a lot! Processes such as diagenesis, chemical decomposition and the existence of metabolically active microorganisms at the deepest and most extreme extent of our exploration lead us to wonder why and how organic matter is preserved for millions of years in rocks.To address this, my research test the limits of what it means to be refractory, labile or biologically available, by exploring the degradation, dissolution and utilization of ancient organic matter in soils, aquatic systems and the deep subsurface.
