Gihan Karunaratne is an architect and academic whose research engages critically with urban transformation, spatial justice, and informal urbanisms, particularly in the Global South. His work explores the intersection of urban change and the lived experiences of marginalised communities, emphasising the socio-spatial dynamics of informality and resilience. Karunaratne foregrounds often-overlooked dimensions of urban life, offering insights into the structural inequalities that shape contemporary cities. His publications with Routledge, including Informal Settlement of the Global South, Resilient Urbanism, and Displaced Urbanism, contribute significantly to scholarly discourse on architecture, urban design, and the complexities of precarity in rapidly evolving urban contexts.
