University Distinguished Professor, Department of Ecology and Evolutionary Biology

I am an ecosystem ecologist with interests in biogeochemistry, soil organic matter dynamics, roots, stable isotope ecology, and climate change.  I work at the interface of the biotic and abiotic worlds, trying to understand how vegetation and microbes both respond to and shape the chemical and physical environment across space and time.
