Biography

I work as a Research Scientist at Institute of Artificial Intelligence, China Telecom (TeleAI), working with Prof. Dell Zhang and Prof. Xuelong Li. Previously, I pursued my Ph.D. degree at University of Macau (UM) and worked closely with SIAT-MMLAB, 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:

General Low-level Vision
Multimodal Understanding
Multimodal Generation

团队不定期招聘研究/工程型实习生，Base地上海，欢迎附送简历联系chxy95@gmail.com。主要方向涉及：

多模态视频生成
多模态视频理解
多模态记忆机制

团队有少量国内联培博士名额，且与英、港、澳地区多个高校及国内工业界有密切联系，表现优秀者可协助博士/工作申请。
