About
Background & research focus
I am currently a doctoral student specializing in artificial intelligence at South China University of Technology (2024–present), under the supervision of Lei Yang . My research interests encompass large language models, data mining, and deep learning.
I graduated from Anhui Normal University in 2021, earning a B.Eng. degree in Internet of Things. That same year, I was accepted into Anhui University, where I ranked first in my major with a total score of 381 (143 in professional courses). In 2024, I was admitted to South China University of Technology to pursue my PhD.
Currently, I am doing further research on LLM privacy and general graph safety. If you are interested in my work, feel free to reach out to me.
