Major research interests of Tasos Zembylas are epistemology of artistic creative practices, Cultural Institutions Studies, and cultural policy. In the 1990s Tasos Zembylas investigated the formation process of the contemporary concept of art. His approach was to study not only relevant discourses and art theories in visual arts, but, equally important, to describe and analyse institutional structures, processes of valuations and other practices taking place in the art world. He thereby developed a practice-oriented and practice-theoretical approach to the sociology of the arts. The close connection between arts and social practices, as well as between art worlds and social structures embodied in cultural activities, led Zembylas in early 2000s to focus on cultural, social, political and economic analysis of arts and culture. His theoretical efforts resulted in the elaboration of an inter-disciplinary approach towards the major topics of cultural institution studies. In addition to his theoretical work, Zembylas has conducted several empirical studies, notably on public funding of the arts in Austria, which dealt with the legal standards prevailing in administrative subsidy procedures as well as the effects of public funding policies. From 2006 to 2008, together with Claudia Dürr, Zembylas investigated the literary writing process from an epistemological perspective. The study focused on the formation and effects of artistic-practical know-how, as well as on the role of professional experience in the creative process. This study led to a general epistemology of artistic creative practices. From 2013 to 2015, together with Andreas Holzer, Annegret Huber, Martin Niederauer and Rosa Reitsamer, Zembylas conducted a similar study on composition processes in the field of contemporary art music. In this case, the focus was on the materiality and processuality of artistic practices. In addition, the synergy of different forms of knowledge (especially tacit knowledge) was systematically investigated. Tasos Zembylas has also published a literary travelogue about Athos. In it he not only addressed religious practices but also the economic management of the Holy Monastery of Vatopedi, which made the headlines in the international press in 2008 in connection with a real estate scandal.
