I am Xiangtai Li (ๆ็ฅฅๆณฐ) and I work as a Research Fellow at MMLab@NTU, S-Lab advised by Prof.Chen Change Loy.
I obtained my PhD degree at Peking University under the supervision of Prof.Yunhai Tong, and my bachelorโs degree at Beijing University of Posts and Telecommunications. I also worked closely with Prof.Zhouchen Lin and Prof.Dacheng Tao.
My research work focuses on several directions, including pixel-wise scene understanding for video/image scene understanding (such as semantic/instance/panoptic segmentation and object detection), their zero/few shot variants, general deep learning methods with applications (such as vision transformer, efficient model design, and neural collapse), and vision meets language (including open vocabulary learning, visual prompting, and visual grounding) and foundation model tuning.
Besides, I am also very interested at aerial image analysis since I am a fun of history and military games.
During my PhD, I conducted research on image/video semantic/instance/panoptic segmentation, as well as several related problems.
Currently, I am looking for Research Scientist Position in the Industry (start from 2024).
Feel free to connect me at lxtpku@pku.edu.cn and xiangtai.li@ntu.edu.sg.
