Through installation, video, sound, and sculpture, Sigurður Guðjónsson explores the materiality of time, motion, and material phenomena. Focusing on overlooked industrial and elemental processes, he reveals the underlying rhythms and temporal structures of matter in transformation. Working with lens-based media, light, and spatial relationships, Guðjónsson amplifies the interaction between man-made machinery and natural forces. Drawing on his background in music, he creates precise sonic environments that anchor each installation and extend its perceptual field. In recent years, the exhibition space itself has become an increasingly central medium in his practice, allowing him to construct multilayered environments that heighten sensory awareness and expand the viewer’s perceptual experience.

Sigurður Guðjónsson represented Iceland at the 59th International Venice Biennale in 2022 with his installation Perpetual Motion, curated by Mónica Bello. In 2018, he received the Icelandic Art Prize for Visual Artist of the Year for his exhibition Inlight, organized by the ASÍ Art Museum. His work has been presented in numerous solo and group exhibitions worldwide, including Francisco Carolinum, Linz, Austria; Wuhan Biennale, Wuhan; National Gallery of Iceland; Reykjavík Art Museum; Scandinavia House, New York; Frankfurter Kunstverein, Germany; Arario Gallery, Beijing; Liverpool Biennial, UK; Tromsø Center for Contemporary Art, Norway; and Hamburger Bahnhof, Berlin.

Since 2025, he has been a professor in the MA program in the Department of Fine Art at the Iceland University of the Arts.
