Dr. Mark Radosevich is professor of soil microbiology in the Department of Biosystems Engineering and Soil Science at the University of Tennessee. He has 20 years of experience in conducting research involving the fate and transport of organic pollutants in soils. During the past ten years he has addressed fundamental questions regarding the ecological role of terrestrial bacteriophage. Recently he was appointed as a research group leader in the area of Water and the Environment within the University of Tennessee Institute for Agriculture. He is responsible for assembling teams and facilitating interdisciplinary research directed at environmental sustainability in agroecosystems. Other recent research topics include the use of biochars as soil amendments, use of phage and phage-encoded proteins as biocontrol agents, and characterizing the ecological role of the Gemmatimonedetes, an abundant but rarely cultivated soil bacterial phylum.
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 NSF and USDA-funded projects studying: 1) microbial carbon assimilation and allocation under drought conditions in southern California grasslands, 2) the effects of seasonal transitions and freezing/thawing on microbial carbon and nitrogen cycling in low and high Arctic ecosystems, and microbial controls on nutrient retention in agroecosystems. His other research interests include: the role of viruses in terrestrial biogeochemical cycles, stability of soil organic carbon fixed by biofuel crops, soil processes in cadaver decomposition islands, and the application of novel stable isotope tracer techniques to study ecosystem processes. Dr. Schaeffer is a member of the Ecological Society of America, the Soil Science Society of America, and the American Geophysical Union.
Dr. Steen is an assistant professor in the Department of Earth and Planetary Sciences at the University of Tennessee, Knoxville, TN. He received his B. S. degree in chemistry from Brown University and M. S. and Ph.D degrees in Marine Sciences from University of North Carolina at Chapel Hill. Dr. Steen’s research is focused on geomicrobiology of aquatic systems, particularly organic matter-microorganism interactions and geochemistry of microbial extracellular enzymes. He is currently leading the performance of two research projects funded by U.S. National Science Foundation. Dr. Steen has published more than 20 peer-reviewed research articles and has given many invited talks.
Dr. Meg Staton grew up in South Carolina in the United States and received her Bachelors of Science in computer science in 2003 from Clemson University. She developed an interested in using her computer background to address biological problems and undertook a plant and environmental science Ph.D from Clemson University, completed in 2007. She has developed a research focus on hardwood tree genomics, particularly chestnut, oak and walnut trees. Her laboratory focuses on analyzing large next generation sequence sets as well as developing online community genomics databases. Meg joined the University of Tennessee in January 2014 as an assistant professor of bioinformatics in the Department of Entomology and Plant Pathology.
