Yunho Choi

I am an AI/Robotics Researcher at Sequor Robotics, Inc, where I work on visual localization of mobile robots. My research interest lies in vision-based robot learning, especially in the decision-making of embodied agents and reinforcement learning.

Previously, I obtained my Ph.D. degree in Electrical and Computer Engineering from Seoul National University (SNU) in 2024, advised by Songhwai Oh at Robot Learning Laboratory. I got my bachelor's degree in Electrical and Computer Engineering with highest honors from SNU as well in 2017.
