Bio

I am a fifth-year Ph.D. student at Department of Statistics, Columbia University and honored to have Professor Yang Feng and Professor Zhiliang Ying as my advisors. I was born in Huainan, which is a small city of China famous for its long history and the delicious tofu there. Prior to Columbia, I obtained my B.S. degree in statistics in 2019 at University of Science and Technology of China (USTC) and was honored to be supervised by Professor Weiping Zhang.

My research interests are mainly related to statistical machine learning, including classification, high-dimensional statistics and variable selection. Specially, I am interested in understanding multi-task and transfer learning problems from statistics perspective. Besides research, I love photography, running, travelling, and reading (especially books about history).
