Matevž Čelik Vidmar, an architect, writer, researcher and cultural producer in the field of architecture and design, was Director of the Museum of Architecture and Design (MAO) in Ljubljana from 2010 to 2020. In 2021, he designed the new European architecture platform LINA. Like its predecessor Future Architecture (also founded by Čelik Vidmar in 2015), LINA aims to exchange and network between architectural institutions and support young professionals. Since 2021, he has been a member of the curatorial team of the European Capital of Culture Temisvar 2023.

MAO, under the leadership of Čelik Vidmar, has become one of the most recognisable and internationally influential Slovenian cultural institutions, having received more than fifteen professional awards in ten years. Among other things, Čelik Vidmar has designed the renovation of the Design Biennial (BIO Ljubljana) and the Centre for Creativity (CZK). The renovation transformed BIO Ljubljana from a standard design exhibition into a living experiment for exploring the potential of design. With the CZK project, which places culture and creativity alongside important economic sectors, MAO has become a national museum with a mission to provide support for the Slovenian creative sector. In 2020, Čelik Vidmar was awarded the Plečnik Medal for his leadership and for establishing MAO in the international community and was named a Southeast European Visionary by BIGSEE.

In 2016, 2018 and 2020, he was appointed Commissioner of the Slovenian Pavilion at the Venice International Architecture Biennial. He has been a guest critic and lecturer at the Faculty of Architecture of the University of Ljubljana, the IUAV University of Architecture in Venice, the Institute of Architecture in Dessau and the Leibniz University in Hannover. Between 2014 and 2018, he was a member of the regional advisory board for the exhibition of Yugoslav architecture from the post-war period entitled H Concrete Utopia: Architecture in Yugoslavia, 1948-1980 at the Museum of Modern Art (MoMA), New York. He is a member of the Advisory Board of the Archipelago Architecture Festival in Geneva and a member of the Advisory Board of the Villardjournal at the IUAV in Venice. He has been a member of numerous competition and prize juries, including the Plečnik Prize and the European Urban Public Space Prize.
