Jangkyu Ju

Ph.D. Student in Computer Science

GT Visualization Lab, School of Interactive Computing - Georgia Institute of Technology

I am a Ph.D. student in Computer Science at the Georgia Institute of Technology, affiliated with the School of Interactive Computing. I am a Graduate Student Researcher in the GT Visualization Lab, advised by Cindy Xiong Bearfield.

My research centers on human-AI interaction and AI interface design, with a particular interest in how information visualization choices shape people's cognition, perception, and trust when they interact with AI systems.

Before joining Georgia Tech, I worked at Hyundai Motor Group as a Data Scientist and Research Engineer, focusing on large-scale user behavior analysis, metrics and dashboard development, machine learning, and personalized in-vehicle interfaces. I hold an M.S. in Behavioral and Cognitive Neuroscience from Korea University.
