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.
