Hyeonjae Gil

I am a PhD student in Mechanical Engineering at Seoul National University, advised by Ayoung Kim. I am currently a visiting PhD student with the Dynamic Robot Systems Group at the Oxford Robotics Institute, hosted by Prof. Maurice Fallon.

My research asks how embodied agents can maintain reliable and useful spatial representations over long periods. I work across lifelong mapping, change understanding, hierarchical 3D scene representations, and egocentric perception, with the long-term goal of building persistent and personalized 4D spatial memory.

My earlier work spans multi-sensor state estimation, LiDAR SLAM, localization, thermal perception, and robotic systems deployed in changing environments.
