I'm a first-year CS PhD student at Stanford. My research is currently advised by Jiajun Wu. I'm interested in world models that are physically consistent, efficient, and operate at the right level of abstraction. I also have a deep interest in physical simulation and inverse physics problems.
Previously, I completed my undergrad at Cornell, where I was fortunate to work with Kevin Ellis and was recognised as a Merrill Presidential Scholar.
