Research
Interests
My research interests focus on the transfer and cycling of
bioreactive material in terrestrial and marine ecosystems, with a
particular emphasis on how naturally occurring perturbation and
anthropogenic activities are impacting biogeochemical cycles. My
research involves a combination of field and laboratory efforts and
involves state of the art equipment and procedures whenever possible. In
our most recent efforts we have used stable isotopes to address carbon
cycling in upland ecosystems at scales varying from foliage to
ecosystems.
