Hello! I’m a second-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.

My research interests lie broadly in safe and reliable foundation models, with a current focus on large language models, multi-modal language models, and diffusion models. By “reliable,” I mean developing methods that help users better trust model outputs. Specifically, my work centers on:

• Detecting and mitigating hallucinations and errors
• Uncertainty quantification
• Interpretability

I am also interested in applying these techniques to broader challenges, including the design of more accurate reward and training signals for post-training and self-verification/improvement.

I am actively seeking internship opportunities for Summer 2026. Please feel free to reach out if there is a potential fit!
