Research Interests
Geochemical cycling in sedimentary and lacustrine environments, implementing stable isotopic analysis in paleoclimatic research. Current research involves Lake Tulane, FL, using hydrogen isotopic analysis to calibrate isotopic fractionation among various biota in a modern system, as well as utilizing this calibration to understand changes in atmospheric circulation and relative humidity in the geologic past. This project is helping to develop hydrogen isotopic measurements as a new proxy for understanding paleoclimate change as it relates to the hydrologic cycle.
