Trained in Fine Arts at the University of the Basque Country, he is a sculptor and lecturer at the universities of Vigo and the Basque Country. His sculptural work addresses the crisis of representation, both in an individual and a social sense. Working with objects and installations close to Minimalism, he addresses concepts such as citizenship and the collective space, as well as the social role of the museum and art. Together with María Luisa Fernández, he founded the CVA collective, active between 1979 and 1985, where he created markedly Conceptual works. In addition to his artistic creation, he has organised and participated in numerous seminars, courses and workshops on artistic production in the new knowledge society and in a new global space, and has curated significant exhibitions at the Artium centre, Vitoria (2012); Museo Reina Sofía, Madrid (2010); and Museo Guggenheim, Bilbao (2007). He is the author of collections of essays, such as Corduras (2007), Ornamento y ley (2007) and Laboratorio de papeles (2006), among others.
Widely exhibited, he represented Spain at Expo 92, Seville; São Paulo Biennial (1994); and Venice Biennale (2001). His exhibitions include the Centro Andaluz de Arte Moderno, Seville (1998); Koldo Mitxelena, San Sebastián (1999); and Museo Reina Sofía, Madrid (2015). His work is included in collections such as the Museo Guggenheim, Bilbao; Museo Reina Sofía, Madrid; Artium, Vitoria-Gasteiz; and MACBA, Barcelona.
