After military service, he moved to Paris in 1962, starting to create sculptural objects and drawings while making a living through his work in photography for fashion magazines.

In 1979 he was a fellow of the center for advanced Visual Studies at M.I.T., and began to create a series of art videos and other documentary works.

His projects have engaged international art audiences in Documenta VI, at the XVII São Paulo Bienal, at his retrospective exhibition organized by the Caixa de Barcelona and Valencia's IVAM, and at the Venice Biennale in 1990.

He is currently launching the Food Cultura Museum [3] and his projects for the Internet, including Grandmother's Recipes and the virtual archive of his collections.
