Seoha Kim

About

I am a PhD student at the University of Melbourne, co-supervised by Prof. Taehyun Rhee and A/Prof. Kris Ehinger. My research aims to perceive and reason over dynamic 3D environments for embodied AI. My interests include functional 3D scene understanding, 4D human-object-interaction understanding, 4D MLLM, world model, and VLA.

Previously, I received my Master's degree from Yonsei University under the supervision of Prof. Youngjung Uh, where I focused on dynamic 3D reconstruction using 3D Gaussian Splatting and NeRF. I also collaborated with Taein Kwon on dynamic 3D hand reconstruction.
