Célia Nouri is a visiting PhD student from the ALMAnaCH team at Inria Paris, and the médialab at Sciences Po. Her research lies at the intersection of NLP and Computational Social Science (CSS), focusing on computational models of online conversations that are contextually grounded and socially aware. She develops contextual NLP models that combine language and graph-based approaches to detect online harms, study moderation practices, and analyze opinion dynamics in online debates.
