About Me
Hi! I am Shiyuan Li (李世源), a PhD student in computer science at Griffith University, advised by Prof. Shirui Pan. My research interests mainly focus on the areas of artificial intelligence and data mining, particularly in graph representation learning and graph foundation model. Previously, I received my master’s degree in computer science from Guangxi University, advised by Prof. Qingfeng Chen, and my bachelor degree of information and computing science from Changsha University.
