Our mission is to advance cutting-edge research and applications of knowledge technologies that support the analysis, modeling and management of knowledge and data.

We have authored and edited numerous scientific books and coordinated several EU projects.

Our technologies have been successfully applied to many practical problems.

We are active in education and transfer of knowledge, and act as a bridge between science and industry in Slovenia and abroad.

Jožef Stefan Institute and Postgraduate School

Jožef Stefan (1835-1893) was one of the most distinguished physicists of the 19th century. He originated the law of the total radiation from a black body.

Founded in 1949, Jožef Stefan Institute is the leading Slovenian scientific research institute, covering a broad spectrum of basic and applied research. The staff of more than 850 specializes in natural sciences, life sciences and engineering.

Department of Knowledge Technologies is one of the seven ICT departments of the institute. Other departments are in the area of chemistry, biochemistry, ecotechnology, nanotechnology, physics, nuclear technology and safety.

Founded in 2004, Jožef Stefan International Postgraduate School offers MSc and PhD programs: ICT, nanotechnology and ecotechnology. Courses are taught in English.
