Biography

Hello. I am a Ph.D. student in Electrical and Computer Engineering (ECE) at the University of Wisconsin-Madison, supervised by Prof. Kangwook Lee. 

Previously, I was a deep learning research engineer at Deep Learning Div. in KRAFTON. Also, I was an AI researcher at Applied AI Lab, NLP Center in NCSOFT Corp.
I received B.S. and M.S. degrees in Electrical Engineering (EE) from Korea Advanced Institute of Science and Technology (KAIST) in 2018 and 2020, respectively, supervised by Prof. Sae-Young Chung.

My research interests lie in Data-centric AI for practical and efficient Language Model Agents. Lately, I have been focusing on developing algorithms to refine data for various models, such as Small Language Models (sLMs), Graph Neural Networks (GNNs), Recommender Systems (RS), and so on.

Research Interest

  • Data-centric AI, Language Model Agent.

  • Other areas, such as Small Language Models (sLMs), Graph Neural Networks (GNNs), Recommender Systems (RS), and so on.

News

  • (Aug. 2025) ✨ Excited to start my new academic journey at UW–Madison!
