Alvin Jinsung Choi

I am a Master student in the School of Electrical Engineering at KAIST, advised by Prof. Hyun Myung.

I am interested in Computer Vision, Robotics, and Embodied AI, focusing on building machines that percepts, reason, and interact with the physical world.

Previously, I completed my Bachelor's degree in Electrical Engineering at KAIST.

Research Interests

My research goal is to advance robotics system to perceive the physical world in a way that is similar to how humans do. Specifically, I am interested in learning and reconstructing the representation of the physical world to faciliate the learning of robot skills. To this end, I am currently focusing on the following topics, but not limited to:
