Ph.D. Candidate · Media and Communication Researcher

I am a Ph.D. candidate in the Department of Media & Communication, Korea University. I study how AI systems communicate, reason about values, and shape public life. My current work asks whether language models can move beyond binary moral choices and propose workable alternatives.

I also use computational methods to study political news, public discourse, and media content.
