My research aims to advance spatial intelligence, enabling AI systems to represent, understand, and ultimately interact with the physical world. To build this foundation, I study 3D/4D scene reconstruction and generation, with a particular focus on Gaussian Splatting. My recent work explores high-fidelity dynamic scene reconstruction from multi-view videos and interactive 4D world generation from limited visual observations.
I am expected to graduate with my M.S. in August 2027 and am currently seeking Ph.D. positions.
