Dr. Sean Schaeffer is an Assistant Professor in the Department of Biosystems Engineering and Soil Science at the University of Tennessee, Knoxville. He obtained a B.Sc. from the University of Utah, a M.Sc. from the University of Arizona, and a Ph.D. from the University of Arkansas. Prior to arriving in Tennessee, he was a Postdoctoral Scholar and Project Scientist at the University of California, Santa Barbara. Dr. Schaeffer is a soil biogeochemist with research interests in the coupled cycling of carbon and nitrogen and how they control the long-term stability of soil organic matter. His current research includes USDA and NSF-funded projects studying: 1) microbial nitrogen assimilation and allocation under drought conditions, 2) the effects of carcass decomposition on ecosystem nitrogen cycles, and 3) nitrogen retention in agroecosystems. His other research interests include: the role of viruses in terrestrial biogeochemical cycles, and the application of novel stable isotope tracer techniques to study ecosystem processes.
