Dr. Sejin Paik is a Postdoctoral Fellow at the Massive Data Institute (MDI) within Georgetown’s McCourt School of Public Policy. Her research areas are in AI-mediated communication, human-computer interaction, AI in journalism, and political psychology. Currently At MDI, she examines how individuals perceive AI-generated political content and audits generative AI models to assess their ability to replicate human-like content.
In her Ph.D. dissertation, “The Digital Soup: The Interplay Between Journalistic and Algorithmic Curation on News Framing Effects,” she explores how differences in algorithmic and journalistic curation strategies influence news framing, perceptions of credibility, and individuals' willingness to engage in politics on social media platforms. Dr. Paik is also involved in applied AI research and product development, where she develops multimodal AI models for real-world applications such as political deepfake detection, personalization algorithms, automated journalism tools, and enhancing accessibility to data-sharing privacy regulations. Her interdisciplinary work in socio-technical product development leverages computational social science to design ethical AI technologies that are human-centered, value-driven, and aligned with the public interest.
She received her B.A. at Emory University in International Studies, M.A. at Stanford University in Computational Journalism and Ph.D. in Communication from Boston University.
