bioanalytical chemistry environment pollution nanomaterials metals

Professor Wilkinson and his group seek to understand the biophysicochemistry of biological and environmental systems. Their work is primarily aimed at improving our understanding of the bioavailability and mobility of environmental contaminants, in part by developing sensitive analytical techniques for heterogeneous systems.
