Research
My scientific interests are directed at quantifying how nutrient and hydrologic cycles control the chemistry of forest soils, drainage waters, and forest productivity. My research focuses on the management of the soil resource in an effort to maximize forest growth and to maintain ecosystem quality. At the stand level this includes questions of fertilizer use efficiency, soil nutrient supplies, and long-term soil quality. At the landscape level this includes the effects of land management and land use change on soil and stream water chemistry, and watershed integrity. My current research includes:
1. Carbon balance of bioenergy production in southern pines.
2. Climate adaptation and mitigation in southern pines.
3. Land use change in the Brazilian Amazon: Impacts on biogeochemical cycles.
4. Spatial covariance in soil carbon and nutrient contents: sampling and estimation.
