I am now working at The Hong Kong University of Science and Technology. Prior to that, I obtained my Ph.D. degree in Computer Science from City University of Hong Kong in 2023 and was a researcher at the same university from 2023 to 2025, supervised by Prof. Rynson W.H. Lau. I received my B.Eng. degree in Computer Science and Engineering (Elite Program) from South China University of Technology in 2019. I did some research at The University of Hong Kong and The Chinese University of Hong Kong during my undergraduate studies.

My research focuses on building robust and multimodal vision applications such as:

• Detecting inconspicuous objects (e.g., mirrors, glass, and camouflaged objects) from real-world data
• Open-vocabulary 3D perception
• 3D vision with imperfect or multimodal data

[Dec. 2024] Two papers are accepted to AAAI 2025.
[Sept. 2024] A paper is accepted to NeurIPS 2024.
[Aug. 2024] We construct OpenScan, a new benchmark for generalized 3D open-vocabulary 3D scene understanding.
[Mar. 2024] A paper is accepted to CVPR 2024.
[Oct. 2023] A paper is accepted to AAAI 2024.
[Jul. 2023] A paper on self-supervised learning is accepted to ICCV 2023.
[May 2023] I pass my Ph.D. thesis defense!
[Mar. 2023] A paper is accepted to CVPR 2023.
[Nov. 2022] Three papers are accepted to AAAI 2023, including two selected for oral presentations, for which I served as corresponding author.
[Oct. 2022] Grateful to be recognized as an Outstanding Reviewer for ECCV 2022.
