Research Summary
Research focuses on changing biogeochemical cycles in terrestrial ecosystems, particularly interested in the nitrogen cycle. In unmanaged ecosystems, a lack of nitrogen often limits plant growth and there are fascinating basic science questions regarding interactions among plants, microorganisms, soils, and hydrology. In managed ecosystems, fertilizers alleviate nitrogen limitations, which helps feed the growing human population, but also generates water and greenhouse gas pollution. There are pressing applied questions regarding our ability sustain yields while reducing nitrogen pollution.
