About Me

I am Assistant Professor at Université Côte d’Azur since 2025, conducting research at the I3S laboratory (UMR 6070) in Sophia Antipolis, France, as part of the joint Inria‑CNRS‑UCA MARIANNE team. My work focuses on advancing machine learning and natural language processing (NLP), with a particular emphasis on cyberbullying detection and prevention on social media, high‑level linguistic analysis, and dialogue modeling.

Previously, I was a Junior Fellow in AI at the 3IA Institute (2023–2024), where I contributed to the EFELIA project, an initiative aimed at strengthening and expanding AI‑related educational modules across disciplines. From 2021 to 2023, I was a postdoctoral fellow within the Wimmics team, focusing on NLP and AI applications for hate speech detection on social media.

I earned my PhD in Computer Science from Aix‑Marseille Université in 2017, developing a content‑based recommender system using NLP techniques as part of the Data, Information Content Management Group (DIMAG) at the LIS Laboratory. I collaborated with OpenEdition to develop BILBO, an automatic reference labeling tool that remains a key component of OpenEdition Lab’s digital toolkit.

I am actively engaged in the academic community, bridging theoretical innovation and practical impact with a focus on developing tools and systems that address pressing societal needs.
