Présentation

I am an assistant professor in Informatics at University of Lorraine, Inspé of Lorraine.

My research is located at LORIA, in MosaAIk team.

Research Interests

My research interests concern Natural Language Processing, and more specifically the questions about the ability of Large Language Models to reason, and the interpretability of Word Embeddings.

My previous publications concern speech recognition, machine translation, sentiment analysis, comparability of documents, fakenews detection, and interpretability of word embeddings
