Zhiyuan Peng (Lucius Peng) is the 2nd-year Ph.D. student at Shanghai Jiao Tong University, supervised by Dr. Xin Yin, Prof. Chenhao Ying and Prof. Yuan Luo. I was grateful to intern at Tencent LIGHTSPEED Studios, MSRA, ByteDance.

My research interest includes Code Generation, Large Language Model, and Software Testing. I have published serveral papers at the top international conferences such as ACL, EMNLP, FSE, and ASE. I developed a few well-known approaches including:

• PlayCoder: Game Code Generation
• RepoGenesis: Zero2One Code Generation
• SolEval and PrefGen: Solidity Code Generation

In 2026, I will lead or participate in the following research topics:

• Code Generation: Coding Model & Agent

💼 Experience
