About
My name is Ujun Jeong. I am a 5th year Ph.D. student at Arizona State University. I am part of the Data Mining and Machine Learning (DMML) Lab, under the guidance of Dr. Huan Liu.
My research focuses on modeling user behavior, such as how interactions shape information flow, community formation, and platform dynamics. I develop computational methods to leverage higher-order and heterogeneous relations in social networks using graph and hypergraph learning. I also use econometric techniques to examine how platform design and cross-platform relations influence user behavior through incentives and responses to external shocks. By combining machine learning with sociological theory, my work aims to derive actionable insights from complex social systems for engaging and safer digital environments.
Before beginning my Ph.D. studies, I was honored to be the youngest captain in the Republic of Korea Air Force, specializing in information and communications. I earned an M.S. in Computer Science with a focus on Natural Language Processing from Kyungpook National University, and completed a B.Eng. in Computer Science and Engineering at Sejong University, supported by a full-tuition scholarship and stipend from the Scholarship Foundation for Future Leaders.
