Adrien Tournier is a Ph.D. student in Science and Technology Studies at CNAM’s HT2S (History of Techno-Science) laboratory in Paris. Mobilising infrastructure studies, his thesis centers on constructing a historical genealogy of 5G, the fifth generation of mobile telecommunications network infrastructure. His research delves into the history of telecommunications in France and explores how the decoupling of virtual machines from their physical hardware gives rise to sociotechnical infrastructuring processes.
