Biography
I am currently a postdoctoral research fellow at National University of Singapore (NUS), working closely with Prof. Gim Hee Lee.
I was a research intern at Shanghai AI Lab in 2024, working closely with Bin Zhao.
I got the Ph.D. degree at Huazhong University of Science and Technology (HUST) in 2024, advised by Prof. Luxin Yan. Before that, I got the B.Eng. degree at Central South University (CSU) in 2019.
I am now working on 2D/3D/4D vision perception & understanding in adverse scenes, if you have an excellent project for collaboration, please email me!

Researches
I like to explore how unmanned systems (e.g., uav and robotic) can emulate human behavior to relieve humans from manual tasks.
Similar to humans, unmanned systems perceive the world via vision sensors and then perform corresponding actions in response.
I realize that unmanned systems work well in ideal environments, but fail in adverse conditions, such as adverse weather, low light, fast motion and so on.
Focusing on these challenging scenes, I have devoted myself to a new research topic: Multimodal-IPUP, i.e., scene imaging, scene perception, scene understanding and scene planning.
1. Regarding the issue of unmanned system, I construct a RGB-Event-LiDAR-IMU multimodality hardware system for 2D/3D/4D adverse scenes, and build a large-scale multimodal dataset under various time and various weather. The research outputs have been published in arXiv. More will be open soon.
2. Regarding the issue of scene imaging, I propose multimodal fusion methods for 2D HDR imaging, 2D frame interpolation and 3D/4D scene reconstruction. The research outputs have been published in ICCV 2025, CVPR 2025, TPAMI 2025, CVPR 2024.
3. Regarding the issue of scene perception, I propose multimodal adaptation frameworks for 2D/3D motion flow and detection. The research outputs have been published in CVPR 2025, TPAMI 2024, ICLR 2024, ICRA 2024, CVPR 2023, AAAI 2023.
4. Regarding the issue of scene understanding, I propose large multimodal vision-language models for 2D/3D/4D reasoning, VQA, dense caption and grounding. The research outputs have been published in arXiv, ICCV 2025. More will be coming soon.
5. Regarding the issue of scene planning, I will work on several action planning of robots based on multimodal vision.
