I obtained my Ph.D. in Mathematics and Computer Science from the Data Science and Mining Team at École Polytechnique, under the supervision of Prof. Michalis Vazirgiannis. In parallel, I work at BNP Paribas CIB. Based in Paris, I am part of the Data & AI Lab within the Quantitative Resarch team of Global Markets, where I conduct fundamental and applied research on graph machine learning for financial markets.
I also hold a Master’s degree in Applied Mathematics from École Polytechnique, a Master of Engineering in Image Processing and Data Science from Télécom Paris, and a Master of Engineering in Telecommunication and Computer Science from Lebanese University.
I am mainly interested in graph representation learning and signal processing. Currently, my work involves modelling the dynamic network of user–item interactions for various downstream tasks, such as market prediction and product recommendation.
