Paleoclimatic and paleo-environmental reconstruction in aquatic environments (estuarine, lacustrine, riverine, and marine) using sedimentological, paleontological, and geochemical data. My expertise includes sedimentary geochemistry, specifically using environmentally-sensitive isotopic tracers (87Sr/86Sr, 18O/16O,13C/12C, and 14C/12C) to document changes in salinity, streamflow, temperature, ocean circulation, and coastal upwelling.
