Bernard Dionysius Geoghegan is a writer, media theorist, and historian of science. His research explores how digital technology--as an ensemble of instruments, practices, inscriptions, and concepts--has shaped the science, culture, and the environment. He's also published on topics including the birth of the computer screen, the rise of digital interactivity from Cold War anxiety and geographies, recent German media theory, the technolgoical infrastructures of spiritualism, critical information theory, and the ideology of smart cities. 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 has curated for the Technosphere Project at the Haus der Kulturen der Welt. 

His first book, From Information Theory to French Theory (forthcoming, Duke University Press) examines how information theory and cybernetics shaped the reform of the human sciences in France and the United States after World War II. He shows how conceptions of communication derived from engineering, allied with technocratic agendas, shape the reorientation of research in fields including linguistics, anthropology, psychotherapy, and semiotics. The book offers a revisionist history of "French Theory" as both the humanities' efforts to come to terms with technical ideas of communications and as a neglected predecessor of the contemporary digital humanities. Published excerpts appear in Grey RoomCritical Inquiry, and The IEEE Annals for the History of Computing

Bernard is currently co-authoring with Francesco Casetti arguing for the mutual production of screens and environments, exemplfied through four key visual technologies (phantasmagoria, cinema, radar, global positioning systems) shaped the production of territories. An excerpt of Bernard's contributions to this project appears in the Summer 2019 issue of Representations.

Before joining King's Bernard taught at Yale University, Coventry University, the Humboldt University of Berlin, and the American University of Paris. 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. S. Department of Education, and the Association for Computing Machinery. He earned a binational Ph.D. from Northwestern University and Bauhaus University Weimar.​
