Biography
I am currently an associate professor in the Department of Applied Statistics at Beijing Technology and Business University. Before joining BTBU, I did postdoctoral research in the Department of Probability and Statistics at Peking University from 2020 to 2022, working with Prof Zhi Geng and Prof Yangbo He. I obtained my PhD in the School of Computer Science at Guangdong University of Technology (2017 - 2020), supervised by Prof Ruichu Cai and co-supervised by Prof Kun Zhang (Carnegie Mellon University). I got my Master’s degree in the School of Mathematics and Statistics at Guangdong University of Technology (2014 - 2017), supervised by Prof Zhifeng Hao. From 2019 - 2020, I was a visiting Ph.D. student in the Department of Philosophy, Carnegie Mellon University.
Research Interests:
