I am Dou Hu, an Assistant Professor at the Communication University of China (CUC). Before joining CUC, I received my Ph.D. degree from the University of Chinese Academy of Sciences (UCAS) and the Institute of Information Engineering, Chinese Academy of Sciences (IIE CAS) in 2025, advised by Prof. Songlin Hu.

My research interests include natural language processing and machine learning. My research goal is to develop more intelligent, efficient, and trustworthy AI systems for language understanding and generation. To achieve this, I currently focus on text representation learning to improve the generalization, robustness, and trustworthiness of language models, with a particular interest in representation learning theory and trustworthy large language models.
