After studying design in the United Kingdom, Pilar Palomer lectured at the Faculty of Fine Arts of the Universitat de Barcelona. Her artistic work, which adopts a Conceptual position, incorporates a language of signs, inscriptions and geometries close to post-Minimalism. She is interested in the idea of exploration, repetition and seriality, which she applies in a variety of ways. She also makes colourful work with figurative references, but without renouncing the Conceptual element.

In 1978, she presented work in Spain's first official participation in the Venice Biennale, which she also exhibited at the Fundació Joan Miró. Her exhibitions include the galleries Joan Prats (1982), Eude (1990) and Barcelona (1996); Faculty of Fine Arts of the Universitat de Barcelona (2013); and in other spaces in the city. Her work is included in collections such as the Fundació Suñol, Universitat de Barcelona and MACBA, Barcelona.
