Ecology & Evolutionary Biology, UTK

Biography

Dr. Richard J. Norby is an Adjunct Professor in the Department of Ecology and Evolutionary Biology. He retired in 2020 as a Corporate Research Fellow in the Environmental Sciences Division and member of the Climate Change Science Institute of the Oak Ridge National Laboratory. He is an ecosystem ecologist with interests in tree growth, forest ecology, carbon and nitrogen cycling, and ecosystem responses to atmospheric and climatic change. He has been conducting experiments on the responses of trees and forests to elevated atmospheric CO2 since 1982, with an emphasis on belowground responses, and was the principal investigator of the Oak Ridge Free-Air CO2 Enrichment (FACE) Experiment. He has been leading research with UTK graduate students on belowground interactions in tropical forests in Puerto Rico, through DOE’s NGEE-Tropics program and Brazil, through the AmazonFACE project. He was the task leader for Sphagnum research on a large-scale manipulation experiment in a spruce peat bog in northern Minnesota  and task leader for Vegetation Dynamics in the Next Generation Ecosystem Experiment in the Arctic. Norby has had a strong interest in fostering cross-disciplinary global change research and improved communication between experimentalists and modelers.

Norby has a B.A. in chemistry from Carleton College and a Ph.D. in Forestry and Botany from the University of Wisconsin. He is a fellow of the Ecological Society of America, the American Geophysical Union, and the Association of Tropical Biology. Norby serves as an editor of New Phytologist and is a Trustee of the New Phytologist Foundation, and he is on the advisory board of the Birmingham Institute for Forest Research in the UK. Norby is the author or co-author of 190 journal articles and book chapters, which have been cited more than 17,000 times. He was recognized with an Outstanding Mentor Award by the U. S. Department of Energy Office of Science in 2007, the UT-Battelle Award for Outstanding Accomplishment in Science and Technology in 2004, and the Scientific Achievement Award of the Environmental Sciences Division, Oak Ridge National Laboratory in 1992.
