# overview
I'm a paleoclimatologist/paleoceanographer interested in using geochemistry, geochemical and climate modeling as tools to study past changes in climate and global biogeochemical cycles, with the goal of learning lessons for our future. We run an organic geochemistry lab equipped with gas chromatography, liquid chromatography and isotope ratio mass spectrometry that are specialized at measuring the composition and stable isotopes of lipid biomarkers or "molecular fossils".
