Mark Dion is an American conceptual artist best known for his use of scientific presentations in his installations. His work examines the manner in which prevalent ideologies and institutions influence our understanding of history, knowledge and the natural world. The job of the artist, according to him, is to “go against the grain of dominant culture, to challenge perception and convention”. By locating the roots of environmental politics and public policy in the construction of knowledge about nature, Dion questions the objectivity and authoritative role of the scientific voice in contemporary society, tracking how pseudo-science, social agendas and ideology creep into public discourse and knowledge production. Some of his well known works include Neukom Vivarium (2006), a permanent outdoor installation and learning lab for the Olympic Sculpture Park in Seattle, Washington.
