I am an Assistant Professor in the Department of Computer Science and Software Engineering at Korea University Sejong Campus. I received my Ph.D. in Computing Education from the Department of Computer Science and Engineering at Korea University Sejong Campus, and my M.A. in Educational Technology from Seoul National University. My research focuses on Generative AI in Education, Pedagogical Alignment, Large Language Models, and Knowledge Tracing. Before entering academia, I worked as an AI engineer in the EdTech industry and served as an elementary school teacher, which deeply shaped my passion for building AI-powered tools that enhance teaching and learning.
