Prof Wickramasinghe obtained his Bachelor’s and Master’s degrees from the University of Melbourne, Australia in Chemical Engineering.  He obtained his PhD from the University of Minnesota, also in Chemical Engineering.  He worked for 5 years in the biotechnology/biomedical industry in the Boston area before joining the faculty of Chemical Engineering at Colorado State University.  He joined the Department of Chemical Engineering at the University of Arkansas in 2011 where he holds the Ross E Martin Chair in Emerging Technologies and leads the Membrane, Science, Engineering and Technology Center (MAST).  Prof Wickramasinghe has published over 100 peer reviewed journal articles, several book chapters and is co-editor of a book on responsive membrane and materials.  He is active in AIChE and was the Meeting Program Chair of the 2014 Annual Meeting in San Francisco.  He has also served on the Board of Directors of the North American Membrane Society.

Prof Wickramasinghe’s research interests are in membrane science and technology. His research focuses on synthetic membrane-based separation processes for purification of pharmaceuticals and biopharmaceuticals, treatment and reuse of water and for the production of biofuels.  Typical unit operations include:  microfiltration, ultrafiltration, virus filtration, nanofiltration, membrane extraction etc.  A current research focus is surface modification of membranes in order to impart unique surface properties.  His group is actively developing responsive membranes.  These membranes change their physical properties in response to changed environmental conditions. A second research focus is the development of catalytic membranes for biomass hydrolysis by grafting catalytic groups to the membrane surface.
