Darko's research focuses at the nexus between environmental and cultural sustainability and situations in which architecture and urban design overlap. His investigations of the concepts of urbanity and sustainable development focus on culturally and environmentally diverse contexts which expose difference and offer encounter with the other. Darko’s research books include Green City (2005, Routledge/UNSW Press; with Low, Gleeson, Green); Urbophilia (2007 the University of Belgrade Public Art Public Space publishers), Cross-Cultural Urban Design (2007, Routledge, with Bull, Boontharm, Parin, Tapie), Another Tokyo (2008, University of Tokyo and ichii Shobou) and eco-urbanity (2009, Routledge).
