My research is focused on the philosophical background of Slavic literatures, i.e. the relation between trends in philosophy of the 20th century and Slavic modernisms. My dissertation traces the development and popularization of the concepts of perestroika (1986-1991), which enabled the transition from Marxism-Leninism to post-Soviet society. I show how similar concepts circulate in academic works (intended for small circles) and science fiction, which became the major genre to communicate the philosophy of perestroika from 1967 to 1986.
