Fahey, Timothy James
Liberty Hyde Bailey Professor
As a forest ecologist, my general scientific interest is in better understanding forest ecosystems, both tropical and temperate. I also serve as the Advising Coordinator for the undergraduate programs in Natural Resources and the Science of Natural and Environmental Systems.

research and scholarship focus
My current research is focused on rhizosphere carbon and nitrogen dynamics, causes of a tropical montane forest ecotone and dynamics of forest soils invaded by exotic earthworms.

teaching
teaching focus
I have principal undergraduate teaching assignments: NTRES 201, Environmental Conservation and NTRES 420/421, Forest Ecology (lecture and lab). I am also involved in graduate teaching through the Forest Sciences graduate seminar (NTRES 616) and the Biogeochemistry and Environmental Biocomplexity Seminar series (Fall and Spring).
