Gennaro Postiglione is professor and dean in Interior Architecture at DAStU/Politecnico di Milano. His research field resides at the intersection between people, places, and practices. This theoretical background also nourishes his research by design activity focused on the adaptive reuse of built heritage, including minor and neglected sites. He is interested in architecture and the way it responds to humans, non-humans, and environmental needs, while reflecting on the discipline’s own principles. He studied architecture at the University of Naples, where he attended a three-year master’s in industrial design soon after completing his PhD. Besides having been involved in many international design workshops and intensive teaching programs, he has been a visiting research fellow at the Oslo School of Architecture and Design in 1994 and 1996, the Norwegian Centre for Design and Architecture in 2009, and the Faculty of Engineering at Lund University (LTH) in 2019, as well as visiting professor at LTH in 2007, the Design Academy Eindhoven in 2014, RMIT University in Melbourne in 2016, and the Technical University of Berlin in 2023. Since 2000, he has taken part in several national and international research bids, e.g.: The Atlantic Wall Linear Museum, MeLA-Museum and Libraries in the Age of Migrations, REcall: European Conflict Archaeological Landscape Reappropriation, Transatlantic Transfers, and Unconventional Affordable Housing which he will present in his lecture. The research investigates the link between unconventional design solutions and affordability (to update the Modern Movement paradigm on housing) and explores the concept of the threshold as a key design element for determining the layers of relationships within unconventional residential buildings. He is a member of several editorial boards and has published extensively.
