CV (updated on Dec. 08. 2021)

Bio.

I am Staff Engineer at Samsung Electronics.

I received my PhD in EECS at Gwangju Institute of Science and Technology (GIST), South Korea, advised by Moongu Jeon in Feb, 2022. I also received a B.S. in Computer Science from Korea Aerospace University, South Korea in Feb, 2016.

I focused on the intersection between computer vision, deep learning and representation learning for visual perception in the context of robot agents and large-scale systems. Specifically, I studied visual perception in unconstrained environments where the performance of visual sensing is largely threatened by various types of degradation such as bad weather, noises, occlusion, and dataset biases. Altogether, this research has set new state-of-the-art standards in terms of recognition-friendly and universalness. As a result, my papers have been published at outstanding computer vision and robotics venues such as ICRA, RA-L, T-NNLS, and T-ITS.
