Dr. Dafeng Hui is Associate Professor in the Department of Biological Sciences at Tennessee State University, Nashville, TN, USA. He received his Ph.D. degree in botany with an emphasis on ecology from the University of Oklahoma and the M.S. degree in agronomy with an emphasis in bio-statistics and genetics from Yangzhou University, China. His research interests lie in the broad areas of plant ecology, global change ecology, ecosystem ecology, agro-ecology, biogeochemical cycling, ecological modeling, and eco-informatics. Specifically, his research focuses on the following areas: (1) climate change effects on carbon, nitrogen, and water cycling in terrestrial ecosystems such as grasslands, forests, and croplands, (2) the effects of agricultural practices on crop productivity and greenhouse gases (such as CO2 and N2O) emissions, (3) simulation of ecosystem carbon, nitrogen, and water cycling using ecological models, and (4) data syntheses on ecosystem productivity, biomass partition, litter decomposition, and stoichiometry of C, N and P in terrestrial ecosystems.
Research Areas:

  • Plant Ecology
  • Ecosystem ecology
  • Global change ecology
  • Carbon, nutrient and water cycling

Current N-related Projects:

  • Effects of biochar and nitrogen applications on switchgrass biomass and greenhouse gas emission
