Hao Liu is a first-year M.S. student in Computer Science at Shanghai Jiao Tong University. My research interests include Code Generation and Large Language Models. Before that, I received my B.S. degree in Data Science and Big Data Technology from East China Jiaotong University.

I have two years of competitive programming experience in ACM/ICPC and related contests. This training has given me a solid foundation in algorithms and data structures, as well as experience in collaborative problem solving.
