My thesis work uses molecular fossils (biomarkers) preserved in lake sediments to interpret paleo environmental change in the Holocene. I am particularly focused on developing a paleo temperature proxy based on bacterial lipids called GDGTs. I utilize a combination of geochemical and genomic techniques to elucidate the relationship between these enigmatic lipids and temperature on both local and broad scales. In doing so, I aim to establish regional temperature calibrations for the GDGT-based proxy that will ultimately be applied to lake sediment cores to produce high-resolution terrestrial paleo temperature reconstructions.
