I am a Ph.D. student at Machine Learning Lab. @ Yonsei Univ., advised by Kibok Lee. My research is broadly in machine learning and computer vision, with a particular focus on deep representation learning. Recently, I have become especially interested in calibration and model selection for vision-language models (VLMs).
