I am currently a scientist at EPFL in the Intelligent Maintenance and Operations Systems (IMOS) lab. Previously, I was working as a data scientist & software engineer at Nagi Bioscience. I have obtained my PhD in Computer Science in 2021 at LIPN, the CS lab of Université Sorbonne Paris Nord (Paris 13) . My PhD project was an industry collaboration with Safran Aircraft Engines. Before, I graduated from ISAE-Supaero engineering school in Toulouse .
My broad areas of interest are unsupervised and supervised machine learning, with a focus on robustness (domain adaptation), interpretability (XAI) and engineering applications. I also like building large-scale data-driven applications and developing advanced algorithms on complex industrial data sets.
You can download my (maybe outdated) CV.
