Christopher Warren Schadt
Senior Staff Scientist
Christopher W. Schadt is a Senior Staff Scientist in the Biosciences Division at Oak Ridge National Laboratory. Dr. Schadt is an environmental microbiologist with expertise in the influence of microorganisms (bacteria, fungi and archaea) on biogeochemical cycles in soils and sediments, as well as their interactions with plant community members. Additionally he has interest and expertise in development of molecular methodologies to track the distribution of activities of microorganisms in these environments. He received his Ph.D in 2002 under the direction of Prof. Steven Schmidt at the University of Colorado, Boulder; proceeding to a postdoctoral appointment and subsequent staff appointments at ORNL. Dr. Schadt also is a Joint Associate Professor at the University of Tennessee in the Department of Microbiology. He an author of over 90 peer reviewed journal articles and book chapters
