Prof. Dr. Jakub Galuszka is Junior Professor and Head of the Chair for Sustainable Cities and Climate Change at HafenCity University Hamburg, where he investigates urban sustainability at the intersection of spatial planning, just transition frameworks, and socio-economic development. His research focuses on settlement development, housing, climate change, and urban mobility, with a strong commitment to advancing equitable and climate-resilient cities. He leads the PSSI research project (VolkswagenStiftung Change!), an international collaboration developing inclusive, climate-sensitive strategies for self-build and incremental housing in rapidly urbanising regions. He is also principal investigator of a DFG-funded project examining the ‘informalisation’ of housing markets in Europe, with particular emphasis on affordability, socio-spatial change, and urban policy. Through his teaching, publications, and applied research, Prof. Galuszka fosters dialogue between academia, local communities, NGOs, and international organisations. His work emphasises participatory approaches, co-production of knowledge, and the development of tools that support sustainable housing and urban planning.
