About

I am Ujun Jeong (정우준), a Ph.D. in Computer Science from Arizona State University. I worked as part of the Data Mining and Machine Learning (DMML) Lab, under the guidance of Dr. Huan Liu.

My research models user behavior in interconnected platform ecosystems, examining how their interactions across platforms reshape information flow, community formation, migration, and broader platform dynamics. I develop multi-method frameworks that combine graph learning, agent-based simulation, econometrics, and time-series forecasting. By building machine learning models grounded in sociological theory, my work aims to derive actionable insights from complex social systems to support engaging and safe 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.
