Welcome to my homepage! 🦇

About me ⛵

I am an incoming Ph.D. student in System Engineering and Engineering Managemant (SEEM) at the Chinese University of Hong Kong (CUHK), Hong Kong SAR, supervised by Prof. Wai Lam.

Prior to this, I received my Bachelor’s degree in Data Science and Big Data Technology from Harbin Institute of Technology, Shenzhen (HITsz) in June 2025 (GPA 91.86/100, rank 10/172).

During my undergraduate studies, it was my great honor to receive the guidance from Prof. Jianghong Ma, Prof. Shanshan Feng at HITsz, and Prof. Sibo Wang at CUHK. I also worked as a research intern at Tencent Weixin Group (WXG), Shenzhen from Sep. 2024 to Jun. 2025, where I was luckily guided by Yuanhao Feng, Dr. Guilin Li, and Bo Wang.
