Current situation
I am currently in the final year of my Ph.D. in the ARCADE team (Apprentissage, Raisonnement, Calcul, Axiomatisation, Décision, Estimation) within the MICS laboratory (Mathématiques et Informatique pour la Complexité et les Systèmes) at CentraleSupélec, part of Université Paris-Saclay.
Research activities
My research lies within the field of process mining, with a particular focus on process discovery. I design algorithms and methods for discovering stochastic process models, such as stochastic Petri nets and process trees, that accurately capture real-world business processes' structural and probabilistic behaviours. My work bridges model inference, formal methods, and statistical techniques to support robust, interpretable, data-driven representations of complex systems.
My contributions include methods for extracting the stochastic behaviours of a model via reachability unfolding, optimization procedures guided by distance metrics between observed and simulated behaviours, and Bayesian inference approaches for learning probabilistic parameters from event logs. These methods are designed to be both data-driven and interpretable, providing robust tools for understanding variability and uncertainty in complex systems.
