Mark WiesnerMark R. Wiesner, professor of Civil & Environmental Engineering at Duke University, has been a pioneer in the applications of nanomaterials to membrane science and water treatment and in examining possible risks posed by these materials to humn health and the environment. He serves as Director of the National Science Foundation/USEPA funded Center for the Environment Implications of NanoTechnology (CEINT).Jean-Yves Bottero leads the International Consortium for the Environmental Implications of NanoTechnology (iCEINT) and an associated French-sponsored eight-year effort on the topic, SERENADE. He is head of France's Geoscience and Environmental Laboratory and specializes in the physical chemistry of organic, inorganic, and heterogeneous contaminants; the physicochemical properties of surfaces; mechanisms of coagulation and flocculation; and water and wastewater treatment.
