My research focuses on how soil and sediment processes in terrestrial and aquatic ecosystems affect watershed carbon and nutrient cycling. A mechanistic understanding of how changing climate and nutrient availability will alter watershed carbon and nitrogen cycling is essential for predicting feedbacks to global climate and predicting nutrient inputs to inland and coastal waters. Towards that end, I use biogeochemical models supported by laboratory and field work to examine how global environmental change alters biogeochemistry at plot, local and regional scales.
