As a forest ecologist, Professor Fahey’s general scientific interest is in better understanding forest ecosystems, both tropical and temperate. He also serves as the Advising Coordinator for the undergraduate programs in Natural Resources and Environmental Science and Sustainability.
Dr. Fahey's current research is focused on forest soil carbon, nitrogen and phosphorus dynamics, tropical montane forest ecosystems and fine root dynamics in forests.
Outreach and Extension Focus
Professor Fahey works with the Hubbard Brook Research Foundation to communicate ecosystem science to policy makers and the public through our Science Links.
In 2015, Fahey's teaching focused on principles of forest ecology and sustainability science.
