Vanessa Bailey is a laboratory fellow at PNNL. Her research focuses on understanding the integrated microbial, chemical, and physical system that comprise soils. To achieve this understanding, she studies how water dynamics within soil pores leads to changes in soil carbon chemistry at pore-, core-, and field scales. This helps resolve the bioavailability of chemically and spatially defined soil carbon to soil microorganisms. Soil microbial communities are a key buffer system against perturbations to the earth from climate change, pollution, and disturbance. Bailey and colleagues have conducted research showing, for example, that the rate at which microbes are transferring carbon from soil to the atmosphere has increased over a 25-year time period. She also manages one of the Department of Energy’s largest coastal research projects, COMPASS, where she is leading efforts to understand the transformations and exchange of carbon and nutrients across the interface between land and sea.
