My lab group use a combination of organic and stable isotopic biogeochemical techniques to investigate the biogeochemical record of environmental change preserved in aquatic sedimentary systems - especially lake and ocean sediments. By looking at organic remains in sediments, I can identify variations in the surrounding vegetation (trees and grasses), the aquatic phytoplanktonic community, as well as the micobial community (bacteria and archaea) that have occurred in the past, and use this information to understand global climate and environmental change.
