My name is Qiaosheng Chen (陈乔晟). Currently, I am a second-year Ph.D. student of Websoft Research Group at the School of Computer Science and Technology, Nanjing University. I received my B.Eng. degree from Harbin Institute of Technology at Weihai in 2021. In the same year, I was admitted to study for a M.Sc. degree in Nanjing University without entrance examination. In 2023, I started my Ph.D. degree under the supervision of Prof. Gong Cheng.
