Angelia Seyfferth, University of Delaware, Newark, DE  19716
Angelia Seyfferth is Associate Professor of Biogeochemistry and Plant-Soil Interactions at the University of Delaware where she works to understand the soil biogeochemical processes that dictate contaminant and nutrient cycling and uptake by plants. Her group is particularly interested in how small-scale soil-chemical processes influence contaminant (e.g., As, Cd, Pb) and nutrient (e.g., Si, P, Fe, S) release or attenuation that have large-scale impacts on human and environmental health. They use advanced analytical techniques such as synchrotron X-ray absorption spectroscopy and imaging to unravel the species distributions of contaminants and nutrients in the rhizosphere and in plant tissues, and mechanisms of uptake by plant roots. Ultimately, they conduct basic research that can be applied to benefit society on a local-to-global scale. https://canr.udel.edu/faculty/seyfferth-angelia/
