Biographical Sketch:

Roni Kasher obtained his PhD from the Hebrew University of Jerusalem, Israel, in 2000. After a postdoc fellowship in the Weizmann Institute of Science (Rehovot, Israel) Roni was appointed a faculty position at Ben-Gurion University of the Negev, Israel. Roni supervised 19 MSc theses, 8 PhDs, and 5 postdoc students. R. Kasher is interested in preparing membranes with improved surface properties and solute transport for nanofiltration, reverse-osmosis and ultra-filtration processes. Organic chemistry knowledge and synthetic chemistry approaches are used to prepare novel and advanced membranes. The aim is to deal with obstacles associated with membrane-based water treatment such as removal of organic contaminants, membrane fouling and biofouling, and membrane stability, while maintaining the salt rejection and flux characteristics of existing membranes. Water technologies that complement membrane processes include sorption processes, organic contaminants in groundwater and freshwater, and monitoring of the organic pollutants in water. Other areas of expertise are peptide synthesis and chemistry, scaling phenomena in water treatment processes, and the effects of organic matter on mineralization.
