Professor Sheldon's research group studies paleoclimatology, global change, and biosphere-climate interactions. The group's research investigates linkages between climate and weathering/soil formation on a variety of spatial and temporal scales using whole rock geochemistry, light stable isotopes, and modeling to understand past climatic and environmental change and biogeochemical processes.
