Professor of Environmental StudiesAdjunct Professor of Biological Sciences and Earth SciencesRichard and Jane Pearl Professorship in Environmental Studies
“I am an environmental and forest ecosystem scientist who has studied air pollution effects in high-elevation forests in New England and New York for the last 30 years. Colleagues and I have examined the cycling of elements such as carbon, nitrogen, calcium and lead as they move from the atmosphere through vegetation and soils and into streams. I am also investigating the impact of biomass removal on forested ecosystems. I teach courses on energy, introductory environmental science and forest biogeochemistry and am the lead author on three introductory environmental science texbtooks.”
