Bernard Dionysius Geoghegan is a Senior Lecturer in the History and Theory of Digital Media (loosely equivalent to associate or w2 professorship)​. An overarching theme of his research is how “cultural” sciences shape—and are shaped by—digital media. This concern spans his writing on the mutual constitution of cybernetics and the human sciences, ethnicity and AI, and the role of mid-twentieth century military vigilance in the development of interactive, multimedia computing.  His attention to cultural factors in technical systems also figured in his work as a curator, notably for the Anthropocene and Technosphere projects at the Haus der Kulturen der Welt. 

Bernard's first book, Code: From Information Theory to French Theory (Duke University Press, Dec 2022) examines how liberal technocratic projects, with roots in colonialism, mental health, and industrial capitalism, shaped early conceptions of digital media and cybernetics. It offers a revisionist history of "French Theory" as an effort to come to terms with technical ideas of communications and as a predecessor to the digital humanities. Published excerpts appear in Grey RoomCritical Inquiry, and The IEEE Annals for the History of Computing.

Bernard's current book project, Screenscapes: How Formats Render Territories, draws on infrastructure studies and format studies to offer a radical account of how digital screens produce global space. It considers the digital interface in terms of articulation, i.e., in its technoscientific formatting of territories, temporalities, and practices as “ecologies of operations.” Excerpts appear in Representations (“An Ecology of Operations”) and MLN  ("The Bitmap is the Territory"). 

Bernard received a binational (cotutelle) PhD in media studies from Northwestern and Bauhaus Universities, for a dissertation advised by Samuel Weber, Bernhard Siegert and Jennifer S. Light. He also studied in Paris with Bruno Latour and Bernard Stiegler.
