Nasrine Seraji completed the Temporary American Centre Building for Frank Gehrys American Centre in Paris. This project and her entry for the Foyer competition set up a dialogue that forms the subject matter of her lecture - the relationship between theory and practice in her work. Nasrine Seraji studied at the AA before founding her own studio in Paris. She has taught at the AA, Columbia and Princeton Universities, and is Professor and Chair of the Architecture Department at Cornell University. NB: Sound disappears temporarily halfway through lecture.1`
