Biogeochemistry is the exciting interface between the biological, geological, and chemical sciences. Many Earth System questions require an understanding of all 3 elements and many new advances and breakthroughs are emerging as experimental and analytical approaches are applied across traditional disciplinary boundaries.
In the Biogeosciences sub-group at USC a variety of biogeochemical elemental and isotopic approaches are used to study an array of modern and paleoecological questions.
Research in the Feakins Lab uses organic geochemical tools to identify biomarkers for terrestrial plants and aquatic algae. Carbon and hydrogen isotopic analysis of lipids extracted from living organisms and from soils, lakes, and ocean sediment reveal insights into biochemical processes and environmental change.
