Hi! My full name is Yubing Ren. I am currently a Tenure-track Associate Professor at the Institute of Information Engineering, Chinese Academy of Sciences. Before that, I received the Ph.D. degree from the Institute of Information Engineering, Chinese Academy of Sciences in 2024, under the supervision of Prof. Yanan Cao and Prof. Wei Ma. My research interests include Natural Language Processing and LLM Safety, with a primary focus on LLM Watermarking and LLM-generated text detection.
任昱冰，预聘副研、硕导，2024年博士毕业，入选信工所优才计划B、博士后国资计划， 现聚焦于研究大模型水印和AI文本检测。
