Marte Johnslien (1977) is a visual artist and researcher who lives and works in Oslo, Norway. She is an associate professor in Ceramic Art at the Oslo National Academy of the Arts, department of Art and Craft. She is the PI of the research project TiO₂: The Materiality of White (MoW), and Co-PI of TiO₂: How Norway Made the World Whiter (NorWhite), in collaboration with art and architecture historian Ingrid Halland (UiB). Johnslien holds a PhD in artistic research and presented the results of her project Circumstantial Sculpture in a solo exhibition at ROM, Oslo, in January 2020. The main project White to Earth, consisted of a series of ceramic sculptures and a book. The project investigated the materiality of titanium dioxide, and how the white pigment travels our systems seemingly invisibly. The work formed the basis for the current research projects TiO₂: MoW/NorWhite.

In 2006, Johnslien spent one year in Lusaka, Zambia, working as an artist, teacher, and researcher at the Art Academy Without Walls. Her studies resulted in the self-published artist’s book Showgrounds (2007), which looked at the history of the Lusaka Expo and its post-colonial architecture. The work was later followed up by another study of exhibition architecture in Africa in the artist’s book Black and White and Everything In-Between (2012), which is an investigation of the Asmara Expo in Eritrea and its complex political history.

Johnslien has participated in exhibitions at the Norwegian National Museum of Art, Architecture and Design, The Astrup Fearnley Museum of Art, Museum of Contemporary Art in Antwerp, and in the 12th Havana Biennial. She has had solo exhibitions at the Lillehammer Art Museum, the Henie Onstad Art Center, Galleri Riis, and the Kristiansand Kunsthall, Norway. She is the recipient of the Einar Granum Art Prize (2012). Her work is included in the collections of the Norwegian National Museum of Art, Architecture and Design, KODE, Bergen, the Henie Onstad Art Center, the Sørlandet Art Museum, and the Lillehammer Art Museum. Marte Johnslien is represented by Galleri Riis, Norway, and FOLD, London.
