Biogeochemistry; plant ecology; ecosystem ecology; land use planning
My research focuses on ecosystem-level biogeochemistry, forest ecology, and watershed analysis. Specific interests include element cycling patterns and processes, comparative soil chemistry in forest ecosystems, linkages between terrestrial and aquatic ecosystems, organic matter cycling and decomposition, chemistry and role of humic acids in forest ecosystems, land-use effects on water quality in large river systems, effects of air pollution, acidic deposition on forested watersheds, carbon cycling, and global change.
