Our group’s research contributes to the fields of environmental nanotechnology and environmental fate and transport of nanoparticles, colloids, and emerging contaminants. We are evaluating and improving nanotechnologies for advanced wastewater treatment applications. We are also assessing the environmental health and safety implications of nanomaterials, including the inherent risks of the nanomaterial itself and the role of nanomaterials as delivery technologies to either alleviate or exacerbate the risks of other emerging contaminants.
