My research focuses on the explainability of graph neural networks and graph retrieval-augmented generation. I got my bachelor's degree from Beijing Language and Cultural University (Beijing, China); and my master's degree from Leiden University (Leiden, Netherlands). Currently, I'm a PhD candidate from Aalborg University (Aalborg, Denmark) supervised by Prof. Arijit Khan and Prof. Yan Zhao.
