I am a Ph.D. student at Chungbuk National University advised by Prof. Young-Seob Jeong.
My research interests lie in Natural Language Processing, with a particular focus on Language Models. I work on understanding and adapting language models, including efficient training and personalized models.
I received my B.S. and M.S. degrees in Computer Engineering from Chungbuk National University, where I was also advised by Prof. Jeong.
