Biography

I am currently a research scientist and lead the NLP research group [photo of JDExplore d-team] at JD Explore Academy. I am also a member of the Doctoral Management Trainee (DMT) program (a top-tier talent program in JD.com, Inc.). I received Ph.D. from The University of Sydney, supervised by Prof. Dacheng Tao (IEEE/ACM Fellow). I was a research intern at Tencent AI Lab, advised by Dr. Zhaopeng Tu and Dr. Longyue Wang. I also worked at Cheetah Mobile as the main developer of the "realtime voice translator" [Demo]. I have published over 40 papers in NLP/ML venues, including ACL, EMNLP, COLING, NAACL, ICLR, ICML, AAAI, IJCAI, SIGIR, CVPR, IEEE TKDE, TNNLS, and TMM, and some of them were applied to industrial products. I served as the Area Chair for ACL 2022 and Session Chair for AAAI 2023 and SDM 2021. I won many AI challenges, including SuperGLUE benchmark, GLUE benchmark, WMT 2022, IWSLT 2021 and WMT 2019.

My research mainly focuses on deep learning for NLP, including large language model pretraining, language understanding, generation, and translation. More recently, I and my group have been focusing on foundation models of general NLP. We start with data, models, objectives, optimization, and better adaptation to various downstream tasks to investigate how to efficiently, sufficiently and trustworthily transfer knowledge from large-scale data to the parameters of the pre-training model. Our model scale has reached GPT-3 level, i.e. 175B.

I am always open for collaborations!

📣 I have several internship positions. Self-motivated students with experience in NLP and PLM are welcome.
