I'am working on ontology of social reality. I'am especially interested in philosophical anthropology, philosophy of action, rule-following problem and philosophy of institutions. My work I lean on papers of such philosophers as: L.Wittgenstein, S.Kripke, E.Anscombe, J.Searle. Beside the analitical stream I use also german anthropological tradition, above all theories of A.Gehlen and H.Plessner. Besides I teach history of philosophy, applied ethics and aesthetics (for non-philosophical disciplines) and I coach critical thinking and business ethics (for managers).
