About Me

Hello! I am Bo Xue (薛波), a third-year PhD student in Department of Computer Science at the City University of Hong Kong. I am very fortunate to be advised by Prof. Qingfu Zhang.

I got my M.S. degree from Department of Computer Science and Technology in June 2021 from Nanjing University, where I was very fortunate to be advised by Prof. Lijun Zhang. I was also a member of LAMDA group, led by Prof. Zhi-Hua Zhou.

I got my B.S. degree from School of Mathematics in June 2018 from Nanjing University. In the same year, I was admitted to study for a M.S. degree in Nanjing University without entrance examination.

I am interested in bandits, stochastic optimization and multi-objective optimization.
