Visual artist, designer and curator. His work, stemming from Constructivism and its graphic tradition, explores the daily precariousness resulting from the construction of the artistic object, employing such materials as newspapers, fabrics, wire, wood and paint to create reliefs and investigate densities, transparencies and the re-composition of signs, often through the use of words. He developed graphic projects for albums, books and magazines, such as “Navilouca,” edited by the poets Torquato Neto and Waly Salomão. He curated several exhibitions by Hélio Oiticica and Lygia Clark in Brazil and abroad. He served as director of the Instituto Nacional de Artes Plásticas at Funarte and founded the Instituto Nacional de Artes Gráficas at the same agency. His works were exhibited in solo shows at LURIXS Arte Contemporânea, Rio de Janeiro(2022); Instituto Tomie Otahke, São Paulo (2017); and the Musée Départemental, GAP, France (2005); and in group shows at CAIXA Cultural, Rio de Janeiro (2011); Kunstetage Kassel, Germany (1990); and the 9th São Paulo Biennial (1967). He lives in Rio de Janeiro.
