I explore the digital dimension of contemporary ‘mobile lives' with a focus on IT ethics. This combines qualitative, often ethnographic studies of everyday practices, social theory and design through mobile, experimental, ‘inventive' engagement with industry and stakeholders. An analytical orientation to intersecting physical and virtual mobilities, blocked movements and immobilities of people, objects and information drives this work. My most recent research brings this perspective to the informationalization of large-scale multi-agency emergency response, which raises opportunities and challenges around social media-based public engagement, agile and ‘whole community' approaches to disaster response, data sharing, data protection and privacy.
