🔥 About Me

Welcome to my personal page!

My name is Yang Fei (费扬), a second-year master student at School of Computing, National University of Singapore, major in Computer Science. I graduated as Shanghai Outstanding Undergraduate from Shanghai Jiao Tong University in 2023.06 with a bachelor’s degree from the Department of Cyber Science and Engineering, SEIEE school. Prior to that, I graduated my high at Huaiyin High School with honor.

I won the Outstanding Undergraduate Scholarship of SJTU 3 times in 2020-2022 (Top 15% in SJTU), also won the Top Cybersecurity Student Scholarship in the fall of 2022. I won Meritorious Award in 2021 MCM, and was selected as Merit Student in my sophomore year.

I am deeply interested in research areas encompassing Graph Algorithm, and Data Mining skills. My passion lies in applying my mathematical and programming expertise to address real-world challenges in network analysis, including the simulation of social, recommender or multi-agent systems. I am also keen to explore the innovative applications of LLMs within these domains.

I have researched in several groups and maintain close communication with professional teachers in different fields. I finished my graduation project under the guidance of Prof. Jiaping Gui at SJTU, I was an enthusiastic participant in the 2022 UCInspire program, participated in DSP LAB lead by Prof. Zhou Li. I am now under the guidance of Prof. Xiaokui XIAO at NUS.
