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.

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.
