Soil biogeochemistry is a broad field, examining the movement of nutrient and toxic elements between nonliving and living materials. My research focuses on how metals and metalloids are sourced from nonliving materials (rocks, minerals) and move via water and air to and from soils. We study natural and human disturbed terrestrial systems, predominantly in the eastern United States. Our laboratory applies x-ray, light, and mass-based instruments coupled with traditional and advanced chemical techniques to measure phases of nutrient and toxic metals in solid and aqueous phases.

McKee
I am a physical oceanographer interested in processes at intraseasonal time scales and their roles in shaping primary productivity. Currently, I am studying variability in the evolution and vertical structure of phytoplankton and biomass at straining regions between mesoscale eddies using biogeochemical Argo floats, remotely sensed data, and Community Earth System Model simulations. These are regions where balances break down and ageostrophic, submesoscale processes with strong vertical velocities become important.

Limaye studies the evolution of landscapes on Earth and other planets, focusing on the role of rivers. Current research topics include river forms, dynamics and deposits; landscape and sedimentary records of climate on Mars and Titan; and feedbacks between landslides and ecology in central Virginia. Tools for this work include remote sensing, geospatial analysis, numerical modeling and laboratory experiments.
