Slobodan Žumer, born in Ljubljana 1945, started his career in physics with BSc in 1967 & PhD in 1973 all from the University of Ljubljana and a postdoc at University of Brussels (1975-76). In the periods 1984-86 & 1992-93 he was visiting scientist & professor at Liquid Crystal Institute, KSU, Kent, USA. Since 1986, he is a professor of physics at the University of Ljubljana, and a scientific adviser at Jozef Stefan Institute. He is the head of the inter-institutional research program ťPhysics of Soft Matter, Surfaces, and NanostructuresŤ coupling Jozef Stefan Institute and University of Ljubljana.

He is also a member of the modeling & simulation group “Physics of soft and partially ordered matter” of the Faculty of Mathematics and Physics at University of Ljubljana. He was the Dean of the Faculty of Mathematics and Physics from 2005-07. In the period 2008-12 he was the president of the International Liquid Crystal Society and since 2014 also it’s Honored Member. He is an American Physical Society Fellow and a member of European Academy of Sciences and Arts. He received the Zois lifetime achievements award for his research in the field of theoretical soft matter physics and the Freéderiksz Medal of the Russian Liquid Crystal Society for the outstanding scientific results in the field of liquid crystals. His research interests are modeling, simulations, & theory of topological soft mater including liquid crystals, polymers, nematic elastomers, colloids, active systems, composites, and their use for optics & photonics.
