Qiyu Wu

Hi there! This is Qiyu Wu, an NLP researcher at Sony Creative AI Lab. Previously I received my Ph.D. from The University of Tokyo, advised by Yoshimasa Tsuruoka and supported by JSPS DC Fellowship. I have served as an Area Chair (Action Editor) for the ACL Rolling Review (ARR), supporting conferences such as ACL, EMNLP, and others. I have also acted as a program committee member (reviewer) for several top-tier conferences including ACL, EMNLP, NAACL, ICLR, NeurIPS, and ICML. Additionally, I co-organized the GenProCC Workshop at NeurIPS 2025. Here is my CV. Reach out to me by wuqiyu576 [AT] gmail [DOT] com, or LinkedIn.

Research Interests

My research focus lies in semantic representation learning for NLP, mainly encompassing better representing word/phrase semantics, sentence semantics, in both monolingual and multilingual contexts. I am also interested in visual-language representation and entity representation. I have published papers at conferences such as ACL, EMNLP, NAACL, ICLR, ICML, AAAI, EACL, VLDB, etc.
