About

Hello! I have recently earned my M.S. degree from the Language & Knowledge Lab at KAIST, advised by Minjoon Seo. I am currently seeking opportunities in a research scientist/engineer role. My main research goal is to build efficient knowledge access system that are applicable to real-world scenarios. Specifically, I am interested in (1) Retrieval systems which can handle complex conditions and multimodal data (2) how to efficiently manipulate representation space (3) Retrieval augmented Language model.
