Biography

I work as a Research Scientist at Institute of Artificial Intelligence, China Telecom (TeleAI), working with Prof. Dell Zhang. Previously, I pursued my Ph.D. degree at University of Macau (UM) and the Shenzhen Institute of Advanced Technology (SIAT), Chinese Academy of Sciences, under the supervision of Prof. Jiantao Zhou and Prof. Chao Dong. During the doctoral study, I interned at Shanghai AI Laboratory and led research efforts in general low-level vision at OpenGVLab, working closely with Dr. Yihao Liu. I was also a member of XPixel Group, where I collaborated intensively with Dr. Xintao Wang. I received my B.E. degree and M.E. degree from Northwestern Polytechnical University (NWPU) in 2017 and 2020.

My research interests include Computer Vision and Large Multimodal Model. Current research topics include:
