Local government reform, regional governance, urban-rural fringe, urban planning and development in China.

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.

Vegetation and landscape effects on nutrient cycling and greenhouse gas emissions from high-arctic ecosystems; land-use change effects on net (sources and sinks) greenhouse gas emissions; modeling of biogeochemical processes (e.g. carbon and nitrogen cycling) in terrestrial ecosystems; impacts of land-use history on contemporary ecosystem dynamics
