Biography

I am currently the Head of Singapore Office at Dexmate, following roles as a Research Fellow at MMLab@NTU (2023–2026) under Prof. Ziwei Liu and previously a Senior Research Scientist at Tencent AI Lab (2021–2023).

I received my Ph.D. from the VILab at Harbin Institute of Technology in 2021, supervised by Prof. Hongxun Yao. During my Ph.D., I also interned at SenseTime Research, mentored by Dr. Wenxiu Sun.

We are actively building our Singapore team and are looking for researchers and engineers with strong backgrounds in robotics and 3D vision. Please feel free to reach out if you are interested.
