Yudong is a research officer in the Department of Statistics, working with Tengyao Wang. Prior to joining LSE, Yudong did his PhD in Mathematical Statistics at the University of Cambridge (degree expected early 2022). His main research interests lie in change-point detection problems, high-dimensional statistics, and sequential and online algorithms. His recent work includes developing efficient online algorithms for change-point detection in high-dimensional data that are observed sequentially. Yudong also has an interest in machine learning and reinforcement learning.
