My fields of interest are robotic perception and 3D computer vision. I have done various related projects using LiDAR sensors and stereo cameras. I also served in the Republic of Korea Army for two years, during which I was deployed to Arab Emirates for eight months as a part of the Army Special Forces.

Graduate Student Intern at Clova AI
May 2020 - Aug 2020
Seongnam, Korea
Implemented a deep learning-based lane detection algorithm. Achieved 93.5% recall rate and 97.8% precision rate for road images with high traffic. Managed a data annotation team for labeling a large complicated Korean road data set.
Graduate Student Intern at NAVER LABS
Sep 2019 - Apr 2020
Seongnam, Korea
The first author of "SpoxelNet: Spherical Voxel-based Deep Place Recognition for 3D Point Clouds of Crowded Indoor Spaces" (IEEE/RSJ IROS 2020).
Preprocessed large, messy 3D point cloud data of VLP-16 LiDAR sensors.
Developed an algorithm that rapidly removes moving objects in 3D point clouds
