Jun Seo | POSTECH GSAI

About Me

I am a Master’s student at the POSTECH NLP Lab (Pohang University of Science and Technology), Republic of Korea, where I am privileged to be advised by Prof. Gary Geunbae Lee and Prof. Hyounghun Kim. My research lies at the intersection of Natural Language Processing (NLP) and AI in Education (AIEd), with a primary focus on Knowledge Tracing and Student Simulation.

My academic journey is deeply rooted in my practical experience teaching high school mathematics. While working with a diverse range of students, I witnessed firsthand the limitations of one-size-fits-all education and realized the critical need for personalized learning. This classroom experience serves as the guiding principle of my research: bridging the gap between advanced AI techniques and real-world educational needs.
