个人简历

I am now a research associated professor at Huazhong University of Science & Technology, School of Electronic Information and Communications, where I’m awarded the East Lake Youth Talent Program Fellowship. Before that, I was a Postdoctoral Researcher at the University of California, Berkeley, Department of Statistics, in 2020, hosted by Prof. Michael Mahoney. I received my Ph.D. from CentraleSupélec, University Paris-Saclay, in 2019, where I worked under the supervision of Prof. Romain Couillet and Prof. Yacine Chitour. I received my B.Sc degree in Optical & Electronic Information from Huazhong University of Science & Technology, China, in 2014, and my M.Sc. degree in Signal & Image Processing from University Paris-Saclay, France, in 2016. My research interests are broadly in (statistical) machine learning, signal processing, random matrix theory, and high-dimensional statistics.
