3/3 Correcting all errors would be time-consuming, and it is unclear whether edits would be retained. I would welcome colleagues’ views on how best to handle this, as it is worrying to see such misleading content circulating. 🌊

2/3 The page raises concerns: it contains numerous factual inaccuracies about my career, and a section titled “Debates and Critiques in Research Field” misrepresents and criticises findings from papers I co-authored, without citing a single peer-reviewed source. 🌊

1/3 I recently discovered, via a search engine, that an article about me has appeared on Grokipedia, described on Wikipedia as an AI-generated online encyclopedia. 🌊

2/2 Thank you to my family, colleagues, students, and partners — @cnrs.fr @sorbonne-universite.fr @iddri.bsky.social — for your trust, rigor, and collaboration. Without you, this honour would not exist. It belongs to you as much as to me. 🌊
