Xin Yin (殷鑫) is the fourth-year Ph.D. student at Zhejiang University, supervised by Prof. Chao Ni. I was grateful to intern or collaborate at ByteDance, Tongyi Lab, and MSRA. I was the core developer of the Code Genesis project in MS-Agent (ModelScope Team, Tongyi Lab) . My research interest includes Large Language Model, Software Testing, and Coding Agent. I have published papers at the top international conferences such as FSE/ISSTA/ICSE/ASE/CVPR/EMNLP/AAAI. I developed a few well-known approaches including:

• SVulD (FSE’23) and MVulD (TOSEM’25): Vulnerability Detection
• [1] (TSE’24) and [2] (EMSE’25): Empirical Study of Vulnerability
• CodeGPTSensor+: LLM-generated Code Detection
• ThinkRepair (ISSTA’24) and ReduceFix (ICSE’26): Program Repair
• Rectifier and RepoTransAgent: Code Translation
• AUGER (ICSE’25), RATester (ASE’25), CasModaTest (ISSRE’25), and JUnitGenie (ASE’25, ICSE’26 Demos): Unit Test Generation
• SolEval (EMNLP’25) and PrefGen (ASE’25): Smart Contract Generation
• READ (CVPR’25) and UGround: Reasoning Segmentation
• SepPrune (AAAI’26): Speech Separation
• CodeGenesis and RepoGenesis: Coding Agent

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

• Software Testing: Unit Test Generation
• Large Language Models (LLMs): Coding Agent
• Lightweight Training Framework
