Among other themes, her work revolves around an investigation into the female identity, in which everyday objects become protagonists. Animated by the effect of light, mirrors and shadows, Valldosera combines and twists them to construct stages that are often dynamic and always based on an extreme position with regard to the limits of credibility.
Apparently simple and accessible (the artist always makes the mechanisms evident), her works are characterised by being complex and subtle at the same time.
Since the middle 1990s, her work has been exhibited in numerous contemporary art biennials around the world, including the Kwang-ju (South Korea), Sydney, Istanbul, Johannesburg, Venice, Yokohama (Japan), Athens, Santa Fe(USA)and Sao Paulo Biennials and the 1997 Skulptur Projekte held in Münster (Germany). In 2000, she presented her work at a retrospective at the Witte de With Centre for Contemporary Art in Rotterdam, and in 2001 at the Antoni Tàpies Foundation in Barcelona, which led to her being awarded the Catalan government’s National Arts Prize in 2003. She is currently preparing an individual exhibition for the Museo Nacional Centro de Art Reina Sofía in Madrid, which will open in 2009.
