I am a forth-year and final-year Ph.D. candidate at the University of Hamburg (Exzellenzuniversitäten), Language Technology Group, advised by Prof. Dr. Chris Biemann, who is the best supervisor I've ever had. Before I join LT group, I got the M.Eng. and B.Eng. in Computer Science at the South China University of Technology (Double First-Class Universities and Disciplines) in 2019 and 2016 respectively. I have worked with Prof. Wenjie Li (She taught me how to do research and be critical.) at the Hong Kong Polytechnic University and Prof. Min Yang (She introduced NLP to me.) at the Chinese Academy of Sciences. Since 2022, I also collaborate with Dr. Ding Liang and Dr. Longyue Wang, from whom I got a lot of valuable advice.
Research Interests:
I have broad interests in Large (Vision) Language Models. We are hiring student assistants. Self-motivated students with experience in NLP or VLP are welcome. I am always open to collaborations!
