I am a CNRS Research Scientist and accredited research director (HDR) based at Ecole polytechnique. My group's research focusses on both statistical physics of complex systems and hydrodynamics at interfaces. I am particularly interested in quantitative finance, economics and social sciences from a physical perspective. I founded and currently hold the Chair of Econophysics & Complex Systems at Ecole polytechnique, see www.econophysiX.com
