About Me

I received my Bachelor’s and Master’s degrees in Science from Hangzhou Normal University (Advisor: Prof. Yu Xia) in 2022 and Zhejiang Gongshang University (Advisor: Prof. Lihui Peng) in 2025, respectively. Over the past year, I have been working as a research intern in the team of Prof. Fei Wu at Zhejiang University, under the supervision of Prof. Yongwei Wang. My research primarily focuses on AIGC forensics, particularly the detection of LLM-generated texts. I am currently seeking a Ph.D. position. If you are interested in my profile, I would be delighted to connect via email for potential discussions or collaborations.
