Summary
👤
Senior🎓
Top SchoolArthur Katossky is a product-focused data scientist and educator with a decade of experience applying machine learning, econometrics, and NLP to public policy and commercial problems. Currently Product Owner for Trajectoire at DREES, he builds statistical models for mid- and long-term evaluation of French retirement policy while bridging stakeholders across government and research. He has a strong teaching pedigree at ENSAI and elsewhere, designing Big Data curricula and hands-on courses in R, Python, ggplot2 and d3.js, and routinely translates complex analytics for nontechnical audiences. Past roles span end-to-end data projects—from automated web-harvesting and SVM-based price forecasting for real estate to founding a local food business—revealing a blend of rigorous statistical training (ENSAE, DTU PhD-level work) and pragmatic product delivery. Colleagues describe him as curious and interdisciplinary: a “big data cocktail with a twist of social sciences” who favors reproducible analytics and practical visual storytelling.
