Research Statement:
Our goal is to understand how vegetation and carbon storage has shifted through time, and what causes it to shift. We examine sediment cores using interdisciplinary methods (pollen and spores, macrofossils, x-ray fluorescence, C-14, Cs-137, and isotopes) to examine how climate and human impacts caused these shifts. We utilize field studies, lab analysis, and understanding of modern analogs from marshes, bogs, lakes, and swamps in the northeastern US, Alaska, and Siberia. With this understanding, we conduct sensitivity experiments with the GISS model to examine climate and human-forced shifts in vegetation.
