I recently completed my M.S. in the Department of Industrial and Systems Engineering at KAIST, where I was advised by Prof. Hwanjun Song. I received my B.S. in Industrial Engineering from Yonsei University, where I worked as a research intern with Prof. Kyungwoo Song. I hold dual citizenship of the United States and the Republic of Korea, and I plan to apply to Ph.D. programs in Fall 2027 as a domestic applicant in the U.S.
My research focuses on efficient and scalable AI systems, with particular emphasis on optimization for large-scale deep learning models. I am interested in improving training and inference efficiency in large language models (LLMs) and vision–language models (VLMs), as well as developing robust and reliable AI systems that perform effectively under real-world constraints.
