Bio: Dr. Fernandez received
his B.A. degree from Hartwick College in 1975. He received a M.S.
(1978) and Ph.D. (1981) in Soil Science from the University of
Maine. He joined the faculty in 1983. He is currently a Professor
of Soil Science. (resume pdf)
Current Research:
The Forest Soils program focuses on
nutrient and metal cycling in forested ecosystems, with particular
attention paid to soil processes. Most of the research in this
program focuses on environmental issues that include the effects of
global climate change, acid deposition, sludge and ash land
spreading, and forest harvesting on the biogeochemistry of forests.
Research activities include field research on regional, watershed,
and plot scales, as well as greenhouse and laboratory studies. This
research is carried out through the efforts of post-doctoral
scientists, technicians, graduate students, and undergraduate
student workers. Funding for research is derived through the Maine
Agricultural Experiment Station at the University of Maine, with
much of the program support by grants from the USDA Forest Service,
US Environmental Protection Agency, National Aeronautics and Space
Administration, and the forest products industry. Graduate students
are typically sought to assist in these studies and to develop their
own research problem that compliments the existing program.
Assistantship support is from departmental assistantships or from
extramural funding.
