My interests include biogeochemical cycling in natural systems as well as the effects of regional and global phenomena (atmospheric pollution, increased carbon dioxide and climate change) as well as localized influences (such as harvesting, fire, fertilization) on biochemical cycling, primarily in forest ecosystems. With regard to soils, my interests include soil-soil solution chemical interactions; factors affecting organic carbon accumulation and loss; nitrogen, sulfur, phosphorus transformations.
