Visiting Professor

My research interests: Machine learning, mean-field games, optimization, control theory, numerical analysis

I am now an associate professor at Université Bourgogne Europe. Before that, I was a post-doctoral researcher at FAU DCN-AvH in 2024. I obtained my PhD degree at Institut Polytechnique de Paris in 2023, my master degree at Sorbonne University in 2020, my engineer degree at École Polytechnique in 2019, and my bachelor degree at Nanjing University in 2016.
