Hwang Seongjin

I am a post-master researcher in AiSLab at SNU, supervised by Prof. Hyun Jong Yang. I earned my B.S. and M.S. degrees from POSTECH in 2022, 2025, repectively.

I am passionate about applying AI to new domains. My master’s research focused on the security of AI training data, and my post-master work explored AI applications in Radio Access Networks (RAN). These experiences strengthened my interest in adapting AI methods to compelling services and practical fields.
