Rune Saugmann Andersen is a post-doc at the University of Tampere, Finland. His interdisciplinary research draws on new media theory, semiotics, and security theory to investigate visual understandings and visual mediation of security. His PhD at the University of Copenhagen explored how new visual media are changing both security politics and scholarship on security, leading to both new security dynamics and new forms of inquiry that challenge text-based understandings of the world and analysis. Currently, Saugmann Andersen is investigating how security is conceptualized in systems employing machine vision in security governance. His work has appeared in Security Dialogue, EJIR, Journalism Practice, European Journal of Communication and JOMEC as well as numerous edited collections, and can be found at saugmann.tumblr.com and on his Academia.edu page.
