CV (Resume)

My name is Ujun Jeong. I am a 4th 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 is centered on the intersection of social media mining and sociolinguistic analysis, where the primary goal is to unravel the structural relationships embedded within social messages. More specifically, I employ Graph Neural Networks (GNNs) and Natural Language Processing (NLP) as key tools to decipher the significant structures intrinsic to social networks. This approach enhances our comprehension of user behavior on social media platforms, especially in terms of the intertextual meanings present in user-generated content, which often comprise informal narratives and personal experiences.


I 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. During my Master's degree, I studied Computer Science with a focus on Natural Language Processing at Kyungpook National University. For my Bachelor's degree, I majored in Computer Science & Engineering at Sejong University with full tuition from the Scholarship Foundation for Future Leaders.
