EHSRC Investigator Detail

Dr. Grassian and her research group are interested in the chemistry of environmental interfaces and are using state-of-the-art techniques to unravel the complex chemistry that occurs at these interfaces. Several ongoing projects include:  the surface science of environmental interfaces; heterogeneous atmospheric chemistry of the components of mineral dust - carbonates, clays and oxides: mineral dust and its impact on global processes - climate, biogeochemistry and health; applications and implications of nanoscience and nanotechnology in environmental processes - remediation, CWA decontamination; Fe nanoparticles in natural systems; impacts of nanomaterials on human health and the environment.
