Bernard Dionysius Geoghegan is a writer, media theorist, and historian of science. In addition to serving as Senior Lecturer (permanent) in the History and Theory of Digital Media in the Department of Digital Humanities at King's College London, Bernard curates for the Technosphere Project at the Haus der Kulturen der Welt. He earned a binational Ph.D. from Northwestern University and Bauhaus University Weimar.

His first book, From Information Theory to French Theory (currently in review) considers the history of cybernetics and the human sciences. It seeks to understand how digital media contribute to the definition of expertise, standards, and research objects with particular reference to how political agendas and third-party funding shape the adaptation of digital technologies and their standards across disciplines. Published excerpts in Grey RoomCritical Inquiry, and The IEEE Annals for the History of Computing have considered the interpretation and application of digital artifacts in areas including linguistics, psychotherapy, historiography, and anthropology. 

Bernard's more recent research activities (including as a curator) focus on media, visuality, and the environment. His current book project, which he is co-authoring with Francesco Casetti, analyzes how four key visual technologies (phantasmagoria, cinema, radar, global positioning systems) shaped the production of territories. Bernard has also written on topics incluidng the rise of networked computing, German media theory, the media infrastructures of spiritualism, the Anthropocene, and the history of human-computer interaction

He's held fellowships at a number of institutions, including the IKKM (Weimar), the DCRL (Leuphana University), the Institute for Research and Innovation (Pompidou Center), the Whitney Humanities Center (Yale University) and his research has been funded by the Mellon Fondation, the German Research Foundation, the U.
