Oswaldo Ruiz (Monterrey, Nuevo León, 1977). Photographer. He studied architecture and postgraduate studies in psychoanalysis, philosophy and art history at the Universitat Autònoma de Barcelona (UAB) and later studied the Master of Fine Arts at Central Saint Martins College, London. Using the darkness of night as the subject of his photographic work, between 2004 and 2012 he portrayed different places on the roads near Monterrey: gas stations, convenience stores, bus stops, and strange buildings. As a result of his artistic residencies in Dublin, Berlin and Santiago de Chile, he developed different projects with which, from a kind of everyday archeology, he explored the light / dark, conscious / unconscious, life / death dualities in his series of medieval towers, ephemeral buildings and anti-monuments. He has had more than twelve individual exhibitions in Mexico and Germany, and has participated in more than fifty collective exhibitions in Mexico, the United States, France, Chile and the Philippines. His work has received different national and international recognitions. It has also been published in various books, magazines and catalogs, and was exhibited at the Paris Photo (2006, 2007) and Madrid Foto (2011, 2012) international fairs.
