I am a Master's student in the MLAI Lab at KAIST, advised by Prof. Sung Ju Hwang. I earned my B.Eng. in Computer Science and Engineering and B.S. in Mathematics from Korea University.

My research interests center on large language models, weight-space learning, model manifold learning, and model adaptation, with a focus on understanding how model representations can be manipulated for merging, initialization, and post-training, and on evaluating when adaptation methods lead to robust generalization rather than reward-specific improvements.

I have worked with Dr. Bruno Andreis and Dr. Bedionita Soro on weight generation and latent-space modeling for foundation models.
