I am a researcher at Orange Research since 2014, specializing in knowledge graphs and their interactions with large language models. For over a decade, I have been designing systems to extract actionable knowledge from enterprise data and improve information retrieval pipelines. I hold a PhD in Computer Science (joint degree, University of Burgundy/University College Dublin) and have led projects such as Telcograph, NORIA, and DAGOBAH, authored more than 40 peer-reviewed publications, and received several international scientific awards. I have been a member of the Orange Expert Big Data & AI community since 2023, and I am actively involved as chair or program committee member in several leading international conferences.

I now lead the Trustworthy AI research program within Orange Research, a natural continuation of my scientific, managerial, and strategic commitments within the Orange Group.
