Born in 1969 in Buenos Aires and a graduate of the Universidad Nacional de Rosario, Hernan Diaz Alonso realized his first projects (a cigar shop, Happening, a fashion shop, Spy, as well as a school, Etnade) in his native country, Argentina. He worked with Enric Miralles in Barcelona in 1996, created his own agency, Xefirotarch, in Los Angeles in 1999, which became HDA-x, and collaborated with the Eisenman Architects agency in 2000-2001. In 2004, his projects were exhibited at ArchiLab and the Venice Biennale. Hernan Diaz Alsonso has had a monographic exhibition at the Art Institute in Chicago and the MAK in Vienna in 2007 and 2008, and is part of the permanent collections of MoMA in San Francisco, and in New York, and Frac Centre-Val de Loire. His activities as a critic, lecturer, and teacher in prestigious schools, such as the Columbia University in New York, the Architectural Association in London, or MIT, and then its position of director of the Southern California Institute of Architecture (SCI-Arc) in Los Angeles have taken him to an international level.
