Hi! I am Jie Wu, an M.S. student at Tsinghua University in the IIGroup, advised by Prof. Yujiu Yang. Currently, I am a research intern with the Qwen team at Alibaba Cloud. Previous, I was fortunate to spend a rewarding year and a half at Microsoft Research Asia, working closely with and learning from Xin Zhang and Haoling Li.

My research centers on LLMs for Code, with a specific focus on:

• Instruction Synthesis and Alignment: Exploring synthetic data generation and alignment (Target-DPO , EMNLP 2025; EpiCoder, ICML 2025).
• Reasoning for Competitive Programming: Enhancing LLM reasoning for complex algorithmic challenges (X-Coder ).
• Environment Scaling for Code Agent: Developing capable agents for terminal and general tasks.

Education

• Aug. 2024 - Jun. 2027 M.Sc., SIGS, Tsinghua University, Shenzhen, China.

• Sep. 2020 - Jun. 2024 B.Sc., School of Computer Science, Wuhan Univeristy, China.
  GPA: 3.98/4.0, Rank: 1/226
