Arctic Tundra

My research in arctic ecosystems has generally focused on how ecosystem carbon balance responds to the thawing of permafrost.  Permafrost soils store tremendous amounts of organic matter that could be lost to the atmosphere with warming and increased microbial activity.  Ongoing research on this topic is in collaboration with Dr. Ted Schuur’s lab at the University of Florida (http://www.biology.ufl.edu/ecosystemdynamics//).
