In 2003, Diaz created a major installation for the Havana Biennial, I Cuba, an installation of free souvenir items emblazoned with the artist's twist on the familiar New York slogan.
He was commissioned by the Public Art Fund, New York's premier presenter of public art, to create 4 large-scale sculptures for the grand concourse in the Bronx (2006).
Most recently, Diaz was the recipient of the prestigious Louis Comfort Tiffany Foundation Award and was selected to participate in a major group exhibition at LACMA, Phantom Sightings: Art After the Chicano Movement, which will travel to Mexico City, Houston, and New York. In 2009 he did a solo project at the critically acclaimed Aldrich Contemporary Art Museum, CT. Diaz has lectured on his work at the Whitney Museum of American Art and the Drawing Center, NY.
His work has been reviewed in publications such as the New Yorker, The New York Times, Flash Art, and Frieze.
