Research Interests: 

My research focuses broadly on controls over carbon and nitrogen cycling in boreal forests.  This has included studies on organic N cycling in soils, successional patterns of fine root production and decomposition dynamics, and the role of vertebrate herbivores in ecosystem function and landscape evolution.  I am also involved with groups exploring genomic approaches to bacterial and fungal community structure and function in boreal soils.  A current interest is the physiological ecology of alder-Frankia-mycorrhizal interactions, and the associated role of alder in boreal forest nutrient cycling dynamics.
