Mediation
I do digital and scientific mediation at the Médiathèque des Jardins de la Culture (Riom, France). Notably, I manage the digital creation space, l'Atelier, and host a monthly online show on Twitch, popularizing scientific topics : « Fil d'étincelles ».
Development
Research
Spring – Summer 2019. For an internship at the Max-Planck Institute for Informatics in Saarbrücken, Germany, I worked under the supervision of Simon Raznewski and Gerhard Weikum on commensense knowledge bases. This resulted in DICE, a framework for extracting and consolidating additional facets about the facts in a knowledge base. The source code is available on GitHub. A web demo is also available.
