About Me
I am a second-year CS PhD student at the Chinese University of Hong Kong, Shenzhen, and I feel fortunate to work under the guidance of Prof. Tianshu Yu. My research focuses on graph-based machine learning and AI applications in scientific domains. I also work closely with Prof. Shu Wu on graph-related research.
Prior to my PhD, I obtained my M.S. in Data Science from the City University of Hong Kong under the supervision of Dr. Ruocheng Guo, and my B.S. in Computer Science from Shandong University under the supervision of Prof. Xuemeng Song.
Research Interests
