MPMWorlds: MPM Simulations for Inferring and Extrapolating Physical Dynamics
Žiga Kovačič, Kevin Ellis
In submission, 2026
[Project]
[Paper]
I'm an incoming CS PhD student at Stanford, advised by Jiajun Wu. I'm interested in hierarchical world models that learn the right level of physical abstraction for each task and co-evolve through interaction. I also have a deep interest in physical simulation.
Previously, I completed my undergrad at Cornell, where I was fortunate to work with Kevin Ellis and was recognised as a Merrill Presidential Scholar.
See Google Scholar for the most up-to-date list.
