About Me

Now I work at Honor Device Co., Ltd. as the project leader (PL) of the On-device VLM Group, focusing on Vision-Language Models and Video Understanding. I received my Ph.D. degree at MMLab@SIAT, University of Chinese Academy of Sciences (UCAS), supervised by Prof. Yu Qiao and Prof. Yali Wang in 2024. And I was a research intern at Shanghai AI Laboratory from 2022 to 2023. I received a B.Eng. degree in Huazhong University of Science and Technology (HUST), Wuhan, China, in 2019.
