Hello! I’m a first-year PhD student in the Computer Sciences department at the University of Wisconsin-Madison, where I am fortunate to be advised by Prof. Sharon Yixuan Li. Previously, I completed my MS degree at Yonsei University in the Electrical and Electronic Engineering department under the supervision of Prof. Kwanghoon Sohn and Prof. Kibok Lee.

I am broadly interested in safe and reliable machine learning that align with human intentions and values. Currently, my research focuses on the safety of Large Language Models (LLMs) and Multi-modal Large Language Models (MLLMs).
