My work focuses on the health, biology, ecology and carbon storage potential of forest, grassland and agricultural soils. I am interested in developing knowledge that allows us to predict how environmental change and management will affect the rates of carbon stabilization and decomposition processes, and hence how the size of soil organic carbon stores change in space and time. Such quantitative knowledge is necessary to connect impacts on soils to consequences for society and the environment, and to inform efforts that seek to better manage soils to restore the benefits they provide. The overall goal of my research is to provide the understanding and data necessary for reliable prediction of global change and management impacts on ecosystems, their feedbacks to the carbon cycle-climate system, and to inform the sustainable management of a productive agriculture.
