Jordi Vivaldi is a writer and theorist based in Vienna. PhD Architect (IOUD, Austria, 2014-18) and PhD Philosopher (EGS (cand.), Switzerland, 2018 - ...), Jordi's areas of research include 20th and 21st century's theory of experimental architecture and technology, as well as various forms of Speculative Realism and New Materialism. His current field of investigation orbits around the notion of "Limes", both in its philosophical and architectural registers. More specifically, Jordi's current philosophical research applies Eugenio Trias' ontological theory of limits to Graham Harman's Object Oriented Philosophy in order to construct a liminal approach to the notion of object. 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", his work has crystallized in several articles, essays and lectures.
