Oliver Leistert joined the Center for Media and Communication Studies (CMCS) as a Research Fellow in May 2011, conducting research in the field of civil society and communications and privacy concerns. Specifically, he is looking at obstacles to safe mobile communications and the pros and cons of different on-line and mobile media tools for communication in protest situations. Oliver's book Generation Facebook. Über das Leben im Social Net (co-edited with Theo Röhle) was published in October 2011 by Transcript Verlag. Oliver is currently finishing a doctoral thesis on cybersurveillance and mobile protest media at the University of Paderborn, Germany. In his thesis, he examines what mobile media is used for, where it fails, to what extend it has an impact, how agency changes, how it becomes a danger for protesters, and what repression may follow its use, as well as further questions, drawing from 50 interviews collected around the world.
