It is often viewed that soils are comprised of static organic matter and inorganic minerals that are subject to hydrological, chemical and biological processes. However, biogeochemical processes of minerals and organic matter and their interactions occur as they physically move on the earth surface at the wide range of spatial and temporal scales. My research goal is to quantitatively integrate the interactions among rocks, minerals, and organic matter in motion and to use this understanding to define and resolve fundamental questions in the geochemical and geomorphic evolution of landscapes and regional to global biogeochemical cycles. Currently, I am studying carbon cycle and weathering in the Chippewa National Forest in Northern Minnesota, Sierra Nevada in California, and the Piedmont in Pennsylvania and Delaware.
