Quentin's research lies at the intersection of Computational Social Sciences, Complex Systems and Data Visualization. It focuses on the reconstruction of multi-level socio-technical dynamics from digital traces, with a particular emphasis on web archives mining and knowledge cartography. This interdisciplinary career has made Quentin as much a field researcher as a data analyst and a digital tool maker. He was previously a member of the Complex Systems Institute of Paris and a member of the e-diasporas project at Telecom ParisTech. Quentin is a core contributor to the free text-mining software Gargantext. His main scientific contributions are the Phylomemy reconstruction process, the Web Fragment framework and the Web Cernes.
