About

Hi, I am a Ph.D candidate in User & Information Lab (U&I Lab), KAIST. My research interests lie at the intersection of Natural Language Processing and Human-AI Interaction, with a particular focus on English education. I am recently interested in how LLMs can support student learning interactions, especially through (1) LLM-based student simulation and (2) personalized learning material generation.

Please feel free to contact me via email {firstname}_{lastname} (at) kaist.ac.kr.
