PhD Student @ Sungkyunkwan University (SKKU) · 성균관대학교 · Korea

I am a PhD student in the Department of Electrical and Computer Engineering at Sungkyunkwan University, advised by Prof. Kae Won Choi.

My research focuses on AI-native next-generation communication networks, with an emphasis on learning-based wireless intelligence, adaptive radio access and network control, and reliable operation under dynamic wireless environments. My current work spans AI-RAN, network foundation models, channel estimation, and wireless resource allocation.
