Marijn Nieuwenhuis is a lecturer in Political Geography at the University of Warwick. His research is at the intersection of geography, philosophy and politics. His current research focuses on the ‘politics of the air’ and the political imagination of sand. He studies these two broad themes in relation to questions over the link between environmental reality and political matters concerning technology, pollution, security, territory and governance. David Crouch’s research and writing crosses a number of fields of cultural geography, social anthropology, cultural and visual studies and art theory. These theoretical areas are engaged through an attention to contemporary cultural change, identity, human creativity, life and space encounters and relations, through ethnographies around landscape, everyday life/leisure and tourism, community involvement and the work of artists. This work includes an interest in space and gentle politics, belonging, disorientation and cultural identity, and human poetic expression in diverse forms of creativity.
