About me

I am a final-year Ph.D. student at the Department of Computer Science in the University of Hong Kong (HKU), supervised by Dr. Lingpeng Kong and Dr. Tao Yu in HKUNLP. I received my Master degree in Fudan University, supervised by Prof. Qi Zhang in FudanNLP Group, and my Bachelor degree in Sun Yat-sen University.

My long-term research objective is to develop artificial intelligence agents capable of reasoning, planning and acting in an effective and efficient way. Recently, my research focuses on below topics:

• Diffusion Language Models

• Complex reasoning and long-horizon planning

• Interacting and understanding LLMs

• Data synthesis principles

I'm expected to graduate before June 2026 and am currently on the job market. I would greatly appreciate it if you could email me if you have any opportunities!
