He received his Ph.D. in 2025 from the GRASP Lab at the University of Pennsylvania, where he was advised by Prof. Kostas Daniilidis and received the CIS department's Best Doctoral Dissertation Award. He is best known for his work on dynamic 4D scene modeling, including MoSca, GART, DynMF, and World Motion Models, which use sparse SE(3) trajectory representations for motion generation and dynamic view synthesis.
“complex, dense motion of the physical world can be compactly approximated by a sparse set of moving coordinate frames — specifically SE(3) trajectories”
