I am a Master’s student at the School of Mechanical, Electrical and Information Engineering, Shandong University. My research interests lie in Federated Graph Learning, Generalized Category Discovery, and Medical Image Analysis. I have published several papers at international journals and conferences (see my Google Scholar).
