Jérémie Poiroux is currently completing his masters in information architecture at the ENS of Lyon. He joined the CSS team at Centre Marc Bloch in February. He will be interning for the next six months towards the completion of his thesis, while participating in the AlgoDiv project, under the supervision of Camille Roth. He focuses on sociological issues raised by the design of recommender algorithms and more specifically will devote part of his time to the representation of filter bubbles on Twitter.
