From 2011 until 2016 he was the head of the Institute of Global and Regional Development at the School of Advanced Social Studies in Slovenia.

He has conducted research and taught at the universities of Berkeley, Bielefeld, Frankfurt am Main, Cassel, Lund, Moscow, Rome, Seoul, and Warsaw.

After 1989 his research and teaching became increasingly occupied with transformation processes in various parts of the world and particularly in Eastern Europe.

The monographs "The United States at the End of the XXth Century" (1991) and "The Rise of the Dragon: The Modernization of South Korea" (1994) as well as the collection "Risks of the Transition" (1994) (in Bulgarian) dealt with these topics.

The synthesis opens the prospect for complex studies on fundamental processes of accelerated commercialization of economy, the democratization of politics, universalization of value-normative systems, digitization of technologies, and the ecologization of thinking and behavior.

The new stage is marked by the concentration of the sociological research interest on global social trends as the outcome of interactions at micro-, mezzo, and macro-social structural levels.
