Short Bio
Since September 2026, I am an Assistant Professor at Institut National des Sciences Appliquées (INSA, National Institute of Science and Technology). I am also a member of the LIRIS lab in the DRIM team.
Before, I was a postdoc researcher at INRIA Saclay (French National Institute for Research in Digital Science and Technology) in the CEDAR team with Oana Balalau and Davide Ceolin (Centrum Wiskunde & Informatica, Amsterdam).
I obtained my PhD in Computer Science from the Jean Monnet University in December 2025. I conducted it at the Hubert Curien Laboratory under the supervision of Antoine Gourru, Charlotte Laclau and Christophe Gravier.
My research is mainly oriented towards Machine Learning and Natural Language Processing, with a particular focus on fairness and the mitigation of bias in models.
