Hello! My full name is Yidan Wang (Eden), and I was born in June 2001. I am currently a third-year Ph.D. student at the Institute of Information Engineering (IIE), University of Chinese Academy of Sciences (UCAS), under the supervision of Academician Binxing Fang and Prof. Yanan Cao. Previously, I received my B.Eng. degree with a major in Cyberspace Security from Shandong University in 2022.

My research primarily focuses on two areas:

• LLM watermarking techniques for AI safety
• LLM attacks and defenses in natural language processing

Open to collaboration and happy to discuss any shared interests！
