I am a Ph.D. student in the Graduate School of Artificial Intelligence at POSTECH, advised by Jaeho Lee in the Efficient Learning Lab (EffL). My long-term goal is to build reasoning models that distinguish relevant evidence from irrelevant information. My current work focuses on understanding the failure modes of reasoning vision-language models under irrelevant information. More broadly, I am interested in reasoning, multimodal learning, and robustness.
