I work at the School of Computer Science as an assistant professor and master’s supervisor now, doing some fundamental research on reinforcement learning and multi-agent systems in the AI lab led by professor Lei Chen (陈蕾). I am also recruiting graduate students, if interested, feel free to email me at sdyang@njupt.edu.cn.

I graduated from the School of Information Science and Technology, Southwest Jiaotong University (西南交通大学信息学院) with a bachelor’s degree in 2013 and from the Department of Computer Science and Technology, Nanjing University (南京大学计算机系) with a Ph.D’s degree in 2020, advised by professor Yang Gao (高阳).

My research interest includes reinforcement learning, multi-agent systems and multi-armed bandits. I have published more than 20 papers at the top international AI conferences/journals such as AAAI, AAMAS, TNNLS, TCYB.
