I am an Associate Professor of Computer Science at the University of Artois and a member of the Centre de Recherche en Informatique de Lens (CRIL). Previously, I worked as a postdoctoral researcher at the Lorraine Laboratory of Research in Computer Science and its Applications (LORIA) in the BIRD team. Prior to that, I held a postdoctoral research position at Tallinn University in the Data Science Group. My research focuses on big graph analysis and explainable artificial intelligence (XIA).

I earned my Ph.D. in computer science from the Faculty of Science of Tunis, University Tunis EL-Manar, Tunisia in 2021. My Ph.D. thesis was conducted in collaboration between the Faculty of Sciences of Tunis, the LORIA at the University of Lorraine, Nancy, and LIMOS at the University of Clermont Auvergne, Clermont-Ferrand. In this thesis, my primary focus was on massive data analysis (big data), complex data (big graphs), and large-scale machine learning.

My research areas include (but are not limited to):

    • Big Data
    • Graph processing
    • Graph representation learning
    • Deep graph Learning
    • Explainable artificial intelligence
