I am an ecosystem ecologist.
I use use a variety of field and laboratory techniques to understand
and predict how ecosystems are shaped by climatic change. Specifically,
I work at the root-soil interface to investigate how atmospheric and
climatic change alters belowground carbon and nutrient cycling. The
ultimate goal of my research program is to improve our ability to
predict ecosystem responses to environmental change and thus better
inform policy decisions.
My research is generally focused on answering two questions: (1) How
does environmental change alter the balance among nutrient limitation,
ecosystem production, and carbon partitioning? (2) How do fine-root
production and mortality affect soil carbon storage and nutrient
cycling throughout the soil profile? My research questions broadly
encompass ecosystems ranging from temperate forests to boreal peatlands
to arctic tundra.
