Portrait of Kunhao Li

Kunhao Li · SCUT / SMU

I am currently a PhD student specializing in artificial intelligence at the School of Software Engineering, South China University of Technology (SCUT), supervised by Lei Yang.

I am also a Visiting PhD Student at the School of Computing and Information Systems, Singapore Management University (SMU), under the supervision of Debin Gao and Guansong Pang. In addition, I am long-term supervised by Di Wu from La Trobe University.

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.

My research interests include large language models, LLM privacy, general graph safety, data mining, and deep learning. If you are interested in my work, feel free to reach out to me.
