I'm a forest soil scientist and biogeochemist whose research has expanded into the limnology  of temperate and polar ecosystems. I am particularly interested in interactions between climate, atmospheric deposition, and the cycling of C, N and P within soils and across the terrestrial-aquatic interface.
