In recent works by Jorge Otero-Pailos, preservation appears free of its historic investment in stabilising architecture. His olfactory reconstructions suggest new architectures that recast notions of hygiene, memory and time. His preservation of pollution acknowledges the fact that, for better or for worse, it is our most durable cultural heritage, replacing the buildings on which it settles as symbols of endurance. His installation 'The Ethics of Dust' was exhibited at the 2008 Manifesta Contemporary Art Biennial. Otero-Pailos is a New York-based architect and theorist specializing in experimental forms of preservation. He teaches at Columbia Universitys Graduate School of Architecture. He is the founder and editor of the journal Future Anterior. His work has been featured in publications such as Artforum, Architectural Record, AA Files, Volume and others. His work rethinks preservation as a powerful countercultural practice that creates alternative futures for our world heritage.l
