I am currently a second-year Master’s student in Software Engineering at Peking University. Prior to this, I obtained my Bachelor’s degree from Wuhan University.

My research interests include Large Language Models (LLMs) and Vision-Language Models (VLMs). Recently, I have been focusing on enhancing the reasoning capabilities of LLMs and VLMs while mitigating hallucination.

📖 Educations

• 2023.09 – Present: Master’s student in Software Engineering under the supervision of Prof. Weiping Li at Peking University.
• 2019.09 – 2023.07: Bachelor of Engineering, School of Electronic Information, Wuhan University.

💻 Internships

• 2024.01 – 2024.05, NIO Shanghai, China.
  Contributed to the development of the LLM framework BI Agent, primarily responsible for intent understanding, task routing, and reasoning using LLMs.

• 2025.04 – Present, Baidu, China.
  Participated in pre-training of search LLM and post-training with reinforcement learning for query rewriting LLM. Primarily focused on compressing LLM chains of thought to reduce inference time for query rewriting LLM.
