Prof. Dr. Jakub Galuszka is a Junior Professor and Head of the Chair for Sustainable Cities and Climate Change at HafenCity University in Hamburg, where he explores urban sustainability at the intersection of city planning, just transition approaches, and socio-economic development. His research focuses on settlement development, housing, climate change, and urban mobility, with a strong commitment to fostering equitable and climate-resilient cities.

He leads the PSSI research project (Volkswagen Stiftung Change!), an international collaboration that develops inclusive, climate-sensitive strategies for self-build and incremental housing in rapidly urbanising regions. He also leads a DFG-funded project on the often-overlooked transformations of “formal” housing markets in Europe, with a particular focus on affordability, socio-spatial change, and urban policy.
Through his teaching, publications, and applied research, Prof. Galuszka contributes to building dialogue between academia, local communities, NGOs, and international organizations. His work emphasises participatory approaches, co-creation of knowledge, and the development of tools that support sustainable housing and urban planning worldwide.
