My research group uses isotope and organic geochemistry to study climate change and carbon cycling in terrestrial, freshwater, and coastal environments. Recently our research has focused in three main themes: 1) Defining isotope signals of methane emissions from local to planetary scales; 2) Understanding the fate of carbon and nitrogen released from thawing permafrost; and 3) Reconstructing records of Holocene natural and anthropogenic environmental change in tropical and Arctic landscapes.
