Research Interests

My research focuses on the terrestrial carbon cycle with an emphasis on carbon cycling in upland and wetland ecosystems. In my research I use radiocarbon with natural abundance and isotopic labeling approaches to determine ecosystem and soil carbon turnover times and track carbon as it moves through plants, into soils, and back to the atmosphere.
