Sejoon Jun

I am a 4th-year undergraduate student at KAIST. My research interests lie in world models and robotics, and I am broadly excited about building intelligent systems that can perceive, predict, and interact with the physical world.

Currently, I am a Visiting Researcher at Northeastern University in Boston, working under the supervision of Prof. Lorenzo Torresani. At the same time, I am a research collaborator with Prof. Yilun Du at Harvard, actively working with Dr. Weirui Ye at MIT.
