Prof. Dr. Krešimir Košutić is a professor at the Faculty of Chemical Engineering and Technology (FCET) University of Zagreb. He earned his M.Eng., M.Sc., and Ph.D. from the University of Zagreb (1991, 1995, 1999). From 1990, he held progressively senior positions at the Department of Physical Chemistry, FCET: technical associate (1990–1992), research fellow (1992–2002), assistant professor (2002–2007), associate professor (2007–2011), and full professor (2016–present). He obtained the “Fran Bošnjaković” Award from the University of Zagreb in 2016 for outstanding results in the field of scientific and professional activities, for the promotion of scientific discipline and profession, and for a special contribution to the transfer of knowledge and the education of young experts in the field of technical sciences. He was the supervisor of numerous undergraduate, graduate, and doctoral theses. Additionally, he is a member of the European Desalination Society, the Croatian Society of Chemical Engineers and Technologists, and the Association of Graduate Engineers and Friends of Chemical Technology Studies in Zagreb. His research interests include the physical chemistry of polymer membranes, their preparation, modification, and characterization, as well as physicochemical water treatment processes: pressure membrane separation processes (reverse osmosis, nanofiltration, ultrafiltration, and microfiltration), adsorption, and coagulation/flocculation.
