Hi, welcome to my website. I am a third-year Ph.D. student at DSLab@POSTECH, under the supervision of Professor Wook-Shin Han. My research lies at the intersection of Natural Language Processing (NLP), Retrieval-Augmented Generation (RAG), and Vision-Language-Action (VLA) models, with a particular focus on advancing VLA capabilities. Previously, my work centered on graph data analytics (such as graph pattern cardinality estimation), efficient join processing, query optimization, and AI for Databases (AI4DB). I received my Bachelor's degree in Electrical Engineering from POSTECH. I received my bachelor's degree in electrical engineering at POSTECH. You can see my CV here for more information
