I am a Ph.D student in 3DLG Lab at Simon Fraser University, supervised by Prof. Angel X. Chang. I also closely collaborate with Prof. Manolis Savva and Prof. Daniel Ritchie. My research aims at designing systems and developing algorithms for understanding and generating interactable and dynamic 3D world from realistic noisy signals. More specifically, I’m interested in

  • 4D foundation world models that understand dynamic events, possess persistent memory and evolve alongside streaming visual content.
  • Compositional, interactable and efficient 3D content generation ranging from object parts to large scenes.
  • 3D vision applications in edge mobile devices, robotics and human-centric AI.
