I am a Research Scientist at LG AI Research. Prior to this, I worked at Korea Advanced Institute of Science and Technology (KAIST) as a Postdoctoral Researcher. I completed my Ph.D. degree in the School of Electrical Engineering at KAIST, advised by Prof. Jinwoo Shin. My research has investigated how to learn deep neural networks with limited human prior knowledge. Specifically, my interests include self-supervised learning, transfer learning, data augmentation, and real-world applications with limited labels.
