ACADEMIC & RESEARCH INTEREST

 My research interests fall into two basic categories: 1) biogeochemical cycling and 2) soils. With regard to the former, my interests include effects of both regional and global phenomena (such as atmospheric pollution, increased carbon dioxide and climate change) as well as more localized influences (such as harvesting, fire, fertilization) on biochemical cycling, primarily in forest ecosystems. With regard to the latter, my interests include soil-soil solution chemical interactions, factors affecting organic carbon accumulation and loss, nitrogen, sulfur, phosphorus transformations, and trace gas emission from soils.
