I am currently Hadamard Lecturer at Université Paris-Saclay in the Topology and dynamics team. My research field is functional analysis and operator algebras. I am particularly interested in analysis, probability and dynamics on von Neumann algebras, noncommutative \(L_p\)-spaces and quantum groups, as well as their applications in quantum information theory.
2013 : Master (Mathematics), Université de Franche-Comté (France)
Advisor: Uwe Franz
2012 : BS (Mathematics), Wuhan University (China)
