My Research Interests are on the fate of organic carbon in the sedimentary record and the use of molecular (biomarker) and stable isotope proxies for palaleoenvironmental reconstructions. Specifically, I am interested in the factors controlling the formation and preservation of organic-rich sequences (source rocks) and conditions leading to their subsequent conversion to oil and gas. The use of biological markers (inherited from extant organisms) to reconstruct the biomass input, and the diagenetic changes in such molecules that allow us to elucidate water column chemistry and REDOX conditions provide powerful tools for understanding past biotas and their environments. The formation of organic rich sequences occur in environments ranging from aquatic/lacustrine to fluviodeltaic/coastal plains to marine settings, each with their own unique characteristics and biota, as well as the additional challenges of evolving biota throughout the geological record.
I also keep busy in my roles as co-Editor in Chief for the journal “organic Geochemistry and chair elect of the Organic Geochemistry Division of the Geochemical Society.
