About Me

I am a Ph.D. student at The University of Hong Kong, majoring in Computer Science.

Previously, I received my Master's degree in Computer Technology from Tsinghua University in 2024 and obtained my B.Eng degree in Software Engineering from Xidian University in 2021. I was a research intern supervised by Jieming Zhu and at Tencent mentored by Junwei Pan and Ximei Wang. I was also a founder member of Deep Research Team at Tongyi Lab.

My research directions are Data Mining and Deep Research Agent.
