About Me

Currently, I am a final-year Ph.D. student at MMLab@SIAT, University of Chinese Academy of Sciences (UCAS), supervised by Prof. Yu Qiao and Prof. Yali Wang. And I was a research intern at Shanghai AI Laboratory from 2022 to 2023.
Before that I received a B.Eng. degree in Huazhong University of Science and Technology (HUST), Wuhan, China, in 2019.

Research Interest

My research interests broadly lie in the areas of Computer Vision and Deep Learning, including:
  • Video-related Applications: Temporal Action/Defect Detection, Temporal Sentence Grounding
  • MultiModal Learning: Video-Language Modeling, Multimodal Large Language Model
  • Long-form Video Understanding: Online Action Detection, Video QA, Video Summarization
  • Publications
