Hello! I am an ML Scientist currently working at Nike in the Search team, in charge of Matching, Ranking and Generative AI initiatives. Before that, I was a Research Scientist in the Cognitive Computing Lab at Baidu Research led by Dr. Ping Li. I obtained my Ph.D. in Machine Learning at Ecole Polytechnique and INRIA under the supervision of Marc Lavielle and Eric Moulines.
