Stéphane Grumbach is senior scientist at Inria, France and is a specialist of data systems. He initially worked on technical questions of information processing in the field of informatics, in particular complex data types, such as spatial, statistical, as well as biological data, and has designed a compression algorithm for DNA sequences. His interests have since evolved to more global questions related to the impact of digital systems on society. His research focuses mostly on the geopolitical implications of the digital, which triggers new imbalances and asymmetries between nations, and the emergence of a control society, while human societies are facing the challenges of a more constrained global environment. The contemporaneity of the awareness of the Anthropocene with the digital revolution, and the contrasting visions promoted in different regions of the world are at the heart of his research. After a long period in China, in 2014 he joined IXXI, the Complex Systems Institute at ENS Lyon, and works in collaboration with the Research Institute on Humanity and Nature, RIHN in Kyoto. He also teaches Digital Economy in SciencesPo Paris.
