Prof. Catherine De Wolf, Vanessa Costalonga, and Clara Blum from the Chair of Circular Engineering for Architecture (CEA) at ETH Zurich explore circular design through digital innovation. De Wolf leads research linking reuse and technology for a regenerative built environment. Costalonga focuses on transdisciplinary and place-based approaches to study how digital fabrication can support material reuse in informal and self-built contexts, while Blum investigates track-and-trace technologies with a focus on digital-physical linkages and data governance for circular-construction supply chains.
