A researcher and member of the Institute for Hazard and Risk Research at Durham University
He obtained a degree in Social Sciences and Economics from the University of Geneva, specialising in Geography. He has been awarded an honoris causa doctorate in Human Geography from the University of Fribourg.
His main lines of research are security and airport border control, security at mass sports events, the imaginary geographies of risk and theorising human territoriality. One of his major publications is Die Videoüberwachung öffentlicher Räume. Zur Ambivalenz eines Instruments sozialer Kontrolle (Video Surveillance of Open Space. The Ambivalence of an Instrument of Social Control, Campus, 2006). Klauser is a media figure who has written articles for newspapers such as 24 Heures and Neue Zürcher Zeitung about the effectiveness of video surveillance and its influence on the private sphere, a theme on which he gave some 30 lectures between 2002 and 2007. He is opposed to the use of cameras in the work place and argues in favour of an increase in police patrols as opposed to video surveillance.
