Liwei Wang

I am an Assistant Professor in Computer Science and Engineering department at The Chinese University of Hong Kong (CUHK). Before coming to HK, I have worked for more than two years as a Senior Researcher in Tencent AI Lab at Bellevue, US.

I got my PhD from Computer Science Department, University of Illinois at Urbana-Champaign, advised by Prof. Svetlana Lazebnik.

The Language and Vision (LaVi) Lab, which I founded at the Department of Computer Science and Engineering at CUHK, conducts research in Natural Language Processing (NLP) and Computer Vision, with a particular emphasis on the intersection of vision and language. Our work encompasses a range of topics including Language+Vision, Large Language Models, Multi-modal Large Models, and Embodied AI. I serve as an Editorial Board member of International Journal of Computer Vision (IJCV). I have also served as an Area Chair in many top AI conferences.

If you want to join LaVi Lab, please send an email to lwwang@cse.cuhk.edu.hk
