I am a CNRS Research Scientist (currently on leave of absence), accredited research director and Adjunct Professor at Ecole Polytechnique. My group develops interdisciplinary, data-driven frameworks, rooted in complex systems and statistical physics applied to economics and finance, with a strong emphasis on bridging fundamental research and real-world applications. In parallel, I serve as COO Portfolio Management at Capital Fund Management (CFM), contributing to the strategic and operational oversight of portfolio construction and research integration. Finally, I co-founded and currently serve as Non-Executive director of Art in Research.
