NAM HYEON-WOO
Hi! I am a PhD student in AMI Lab @ POSTECH. I am advised by Prof. Tae-Hyun Oh. I received B.S. and M.S. in Electrical Engineering at POSTECH. I worked with Byeongho Heo, Dongyoon Han, and Seong Joon Oh at NAVER AI LAB.
I am interested in Trustworthy and Responsible AI, including security, robustness, Interpretability, and the science of deep learning to understand AI. Also, I focus on the understanding and evaluation of large language model (LLM) and vision language models (VLMs).
