Bio: Dr. Dail received his
B.S. degree from the University of New Mexico in 1991. He received
a Ph.D. degree (1997) from the University of Geogia. He is
currently an Assistant Professor of Soil Microbiology.
Current Research:
Microorganisms are key contributors
to nutrient cycles in both terrestrial and aquatic ecosystems. My
research focuses on the role of soil microorganisms in the
transformations of inorganic and organic compounds in natural and
disturbed systems. Specifically, I am interested in the fate of
atmospherically derived C and N in forest ecosystems and the
microbial response to elevated inputs of these biologically
important elements. It is clear that fossil fuel burning,
agricultural practices and other land-use changes affect the
abundance of CO2 and oxides of N (NOx) in our atmosphere. Soil
microorganisms serve as both source and sink for these C and N
compounds and understanding the biogeochemistry of these elements in
soil and the role of microorganisms is vital to estimating the long
terms effects of our activities. I use stable isotope pulse labeling
in combination with NMR spectroscopic techniques to gain insight
into rates and resultant structures of immobilized C and N.
