Tizian Rein (born 1997 in Rhöndorf) is an architect working at the intersection of computational design, repair logics and architectural heritage. He studied at TU Munich, ETH Zurich and TH Cologne. His master’s thesis “From Structure to Action: Machine Reasoning and the Logics of Repair” explores how AI-driven design processes can support preservation, repair and transformation of buildings. He has worked at the Professorship of Digital Fabrication (TUM) and at Gramazio Kohler Research (ETH Zurich), and currently operates independently focusing on building transformation and research-led design practice.
