Ujun Jeong specializes in data mining, machine learning, and social computing. His research addresses challenges like misinformation detection and user behavior modeling. His work has gained recognition in Science Magazine, ACM Tech News, and Research Professional News, with insights into user migration to alternative social media platforms like Bluesky Social. Ujun has been honored with the 2022 Outstanding Service Award from WSDM for his leadership in the research community. He has published in top conferences such as ICWSM, SDM, and IEEE Big Data and collaborated with experts in social science and economics. Prior to his academic career, Ujun was honored with the distinction of being the youngest captain ever to serve in the Korean Air Force with a specialization in information and communication.
My research focuses on modeling user behavior on social media platforms and understanding how their interactions shape information dynamics and community structures. By leveraging advanced graph mining techniques, including hypergraph-based frameworks, I analyze higher-order interactions to uncover patterns in content sharing, community formation, and user credibility. I also explore the interplay between multiple platforms, investigating how their unique features and economic dynamics influence user engagement and ecosystem interdependencies. My work incorporates temporal and relational modeling to study user interactions across networks, capturing both micro-level behaviors and macro-level trends. This research supports applications in misinformation detection, personalization, recommendation systems, and the design of safer, more engaging digital environments.
