Andrew J. Friedland

Academic Appointments

Professor of Environmental Studies
Richard and Jane Pearl Professorship in Environmental Studies

“Andrew Friedland is 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. He and colleagues 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. He has also studied the impact of biomass removal on forested ecosystems. He teaches courses on energy, introductory environmental science and forest biogeochemistry and is the lead author of an introductory environmental science texbtook and a primer on grant proposal development and writing.”
