About Me
I am a Ph.D. student in Computer Science at the National University of Singapore (NUS), advised by Prof. Wei Tsang Ooi and Prof. Camille Simon Chane. Previously, I conducted research with Prof. Stefan Leutenegger and Prof. Matthias Nießner at the Technical University of Munich (TUM), where I earned an M.Sc. in Robotics, Cognition, and Intelligence (with distinction). I also hold a B.Eng. in Vehicle Engineering from Tongji University, Shanghai.
My research lies at the intersection of 3D computer vision and multimodal, large-scale deep learning. I explore how heterogeneous signals, including language, depth maps, point clouds, and event streams, can be fused to perceive, model, reason about, and generate rich 3D environments.
