Zhiyuan Peng (彭志远/Lucius Peng) is the second-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 LIGHTNING Studios and MSRA.

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

• SolEval and PrefGen: Solidity Code Generation

In 2025, I will lead or participate in the following research topics:

• Code Generation : Agentic Code Gen, Smart Contract
• Large Language Models (LLMs): Agent, GUI-Testing
