Zhejian Lai (赖哲剑)

I received my B.Sc. degree from Dalian University of Technology in 2023, and during my undergraduate years, I actively participated in several Programming Contest, including ICPC and CCPC. Furthermore, I was honored to be admitted to pursue my M.Sc. degree at School of Computer Science, Nanjing University without entrance examination. Currently, I am a member of the NJUNLP Group, working under the supervision of Prof. Shujian Huang.
