ECONOPHYSICS & COMPLEX SYSTEMS

EconophysiX: Recherche

ABOUT US

We are a dynamic interdisciplinary research group led by Michael Benzaquen and based in the heart of Paris. Our research sits at the crossroads of statistical physics, quantitative finance, economics, and complex systems. We combine theoretical modelling with a strongly empirical approach to explore a broad range of topics, including market microstructure and price formation, market impact, wealth and income inequalities, social dynamics, environmental sustainability, and macro-financial networks.

Through our collaborations with Capital Fund Management and the Institut Louis Bachelier, we benefit from a vibrant academic ecosystem and close interactions with a large community of world-leading experts in quantitative finance and data-driven modelling.

A New Chapter for Econophysics Lab

The Econophysics Lab is entering a new phase and will no longer be affiliated with École Polytechnique. This transition reflects the Lab’s evolving interdisciplinary positioning and its ambition to pursue its activities in an environment better aligned with its future development. We are pleased to continue our long-standing collaboration with our key partners, the Institut Louis Bachelier and the Fondation du Risque, whose continued support remains central to the programmes they accompany. We look forward to this new chapter with confidence and ambition!
