Lijun Wu is a Researcher in Shanghai AI Laboratory, an adjunct Ph.D. supervisor in Shanghai Jiao Tong University,Fudan University, Zhongguancun Academy. Previously, he was a Research Scientist in ByteDance Seed, a Senior Researcher in Microsoft Research. He was a member of joint Ph.D. program between Sun Yat-sen University and MSRA, advised by Dr. Tie-Yan Liu and Prof. Jianhuang Lai.
His research interests cover LLMs/MLLMs and AI4Science. His works are published in Nature Communications, Nature Machine Intelligence, TPAMI, NeurIPS, ICML, ICLR, ACL, KDD and so on, with near 10000 citations. He served as Evaluations and Datasets Track Chair for NeurIPS 2026. He has also served as AC in ICML, ICLR, NeurIPS, KDD, ACL, EMNLP, NAACL and so on. He has received numerous prestigious awards, including the 2018 MSRA Ph.D. Fellowship. He secured 8 championships in the WMT2019 Competition. He led team to create the BioT5 series of multimodal biomolecular models, with more than 300k downloads, winning 1st and 2nd place in the ACL 2024 Language+Molecule Shared Task. His directed to develop OpenDataArena, the first LLM post-training data value benchmarking platform in the world. His team secured 2nd place in the 2025 NeurIPS CURE-Bench Internal Reasoning Competition. His research innovations have been translated into practical products. Notably, R-Drop was deployed in Microsoft Translator across over 20 translation tasks and was widely used in business scenarios at companies like Tencent, Baidu, Meituan. Furthermore, he participated in the development of the worldβs first Chinese-English translation system to achieve human parity in 2018.
