Melanie Mayes is Joint Faculty with the Climate Change Science Institute and the Environmental Sciences Division at the Oak Ridge National Laboratory. She conducts interdisciplinary research in carbon and nutrient cycling and in the fate and transport of metals, organics, and other contaminants in soils and rocks. She designs experiments to build better models of natural processes and is interested in diverse research at the intersection of water, minerals, solute chemistry, and biological cycling.

Her current research includes developing a mechanistic soil carbon cycling model that includes measurable soil carbon pools, sorption and desorption of dissolved organic carbon, and extracellular enzyme-facilitated decomposition of organic matter. The project also uses neutron reflectometry and molecular dynamics simulation to synergistically derive information on the molecular-level structure of organic carbon stabilized on soil minerals. She is actively involved with contaminant fate and transport, with two projects investigating the fate and transport of radionuclides and explosives, respectively, in aquifer materials at Departments of Energy and Defense facilities.

Mayes is the 2011 recipient of the University of Tennessee Earth and Planetary Sciences Young Alumna Award, the Stanley I. Auerbach Award for Excellence in Environmental Sciences from the Environmental Sciences Division at Oak Ridge National Lab, and was named an Associate Editor of Excellence by the Soil Science Society of America Journal.
