I am interested in characterizing and understanding biogeochemical cycling in natural systems, especially the role of microorganisms in waters, soils, and sediments.  Due to observed and predicted increases in temperatures and hydrologic activity in the Arctic, this work helps us to understand how climate change will impact the terrestrial landscape of high latitude environments.
