Biography

Hello. I am a deep learning research engineer at KRAFTON. Before joining KRAFTON, 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 safe, practical, and efficient deep-learning models. Lately, I have been focusing on developing algorithms to refine data for various models, such as Large Language Models (LLMs), Graph Neural Networks (GNNs), Recommender Systems (RS), and so on.
