Research interests

I work on learning systems, from 3D perception to foundation models.

I completed my Ph.D. at Carnegie Mellon University, advised by Kris Kitani, with a focus on multi-view geometry and 3D human pose estimation. In December 2022, I joined Waymo to work on 3D perception for autonomous driving.

I’m now exploring foundation models, post-training, and reinforcement learning through hands-on implementations and experiments.
