I am a Ph.D. student at School of Data Science and Engineering, East China Normal University (ECNU). I am co-advised by Prof. Aoying Zhou and Prof. Chengcheng Yang. I am currently a Research Intern at Tencent. Proior to this, I worked in Taobao, Alibaba Cloud, PingCAP. It was a great pleasure to collaborate with technical experts like Yuanjia Zhang during my internship. I also visited the Database Research Group at Hong Kong Baptist University (HKBU) and collaborated with IEEE Fellow Prof. Jianliang Xu. My current research interests focus on Query Optimization (QO) in relational database systems.
