I’m a Ph.D. candidate in Computer Science and Engineering at the University of Michigan, advised by Stella X. Yu. I received my B.S. in Electrical Engineering from National Taiwan University. I study robot learning and visual perception in real-world settings.
Robot learning. I am interested in scalable learning from diverse data and experience, with human motion as one example of a useful prior. My current work focuses on contact-rich interaction and humanoid whole-body control.
Perception. I study spatial and dynamic understanding from partial observations, semantic localization, and fine-grained understanding of embodied video.
Optical flow must share evidence across pixels without mixing different motions. Instead of matching fixed grid cells, we learn the units of correspondence: each unit gathers evidence from the pixels it represents and returns its motion to them, with the largest error reductions where no match is visible and near motion boundaries.
We turn getting back up into a behavior the robot can adapt and steer. A visual diffusion model lets us guide heading, timing, and route at test time, while a depth-aware controller carries out the recovery on a real Unitree G1.
Where to Hitch? Finding Small, Rare Parts Across Long Spatiotemporal Contexts

Finding a tiny part in a long video can be surprisingly difficult. HitchIt chooses useful views and tracks visual examples to locate parts such as trailer hitches without task-specific training.
