Keller Easterling is an architect, professor at Yale, and one of the most eloquent theorists of architecture and design. In Medium Design (Strelka Press, 2018) Easterling argues that design tools are often inadequate to address contemporary chemistries of power. Medium Design treats space as an information system and a mixing chamber for social, political, and technical networks. It inverts a typical emphasis on object over field, in order to prompt innovative thought about both spatial and non-spatial problems. The session is made possible by the Swiss Architecture Museum (S AM).
