I am a first-year CS Ph.D. student at National University of Singapore (NUS), supervised by Prof. Min-Yen Kan and Prof. Soujanya Poria. Previously, I obtained my Master’s degree in Computer Science and Bachelor’s degree in Inforamtion Engineering from Shanghai Jiao Tong University (SJTU), fortunately advised by Prof. Weinan Zhang. I also work closely with Dr. Wenyue Hua, Prof. Liangming Pan, and Prof. Muning Wen.

Recently, my research mainly focus on LLM reasoning and AI agents, especially:

Reinforcement learning for reasoning models and agentic LLMs.
LLM with memory augmentation for long context understanding.
LLM-based multi-agent collaboration and social reasoning.

I am looking for 2026 summer research internship globally! Feel free to reach out to me if there is an opportunity that you believe I am a good fit, or you are interested in academic discussion / collaboration.
