Jordi Vivaldi is a writer, philosopher and architectural theorist based in Vienna. PhD Architect (IOUD, Austria) and PhD Philosopher (EGS (cand.), Switzerland), Jordi's areas of research include 20th and 21st century's theory of experimental architecture, art and technology, as well as various forms of Speculative Realism and New Materialism. In particular, his current field of investigation orbits around the notion of ""Limes"" together with associated terms such as ""finitude"", ""determination"" and ""reduction"", both in its philosophical and architectural registers. More specifically, Jordi's work applies Eugenio Trias' ontological theory of limits to Graham Harman's Object Oriented Philosophy in order to construct a liminal approach that is both com-pressive and ex-pressive. From an architectural perspective, Jordi's research focus in articulating the concept of ""Limes"" as a contemporaneous form of space associated with our current subjectless condition, particularly in relation to the design of the floor as an architectural element. Jordi is currently working as theory faculty and researcher in several international universities such as IaaC in Barcelona, Bartlett in London, PROPUR in Buenos Aires and IOUD in Innsbruck. Besides his curatorial tasks as editor in chief of the architectural magazine ""IaaC Bits"" and his book on The Threefold Logic of Advanced Architecture (co-authored with Manuel Gausa), his work has crystallized in several articles, essays and lectures.
