I am a Ph.D. Student at the Department of Systems Engineering and Engineering Management, The Chinese University of Hong Kong (CUHK), co-supervised by Prof. Jeffrey Xu YU and Prof. Hong Cheng. Previously, I obtained my Bachelor’s degree from Wuhan University in 2021.

My research interests lie in graph data analytics, especially for subgraph matching and graph mining algorithms.
