Hello everyone, my name is Zhongjian Zhang. Currently, I am a second-year Ph.D. student from Beijing University of Posts and Telecommunications (BUPT), supervised by Prof. Chuan Shi.

My research interests primary focus on trustworthy graph machine learning and large language models. Specifically, my current research is mainly about the development of graph foundation model.

If you have any questions regarding my work or are interested in collaborating with me, please contact me via email.
