Woosang Kim
I am a spatial data scientist with a research background in human–computer interaction and haptics.
I currently work at NTT DOCOMO, analyzing geospatial population data and supporting infrastructure operations for Mobile Spatial Statistics.
My broader research interests include multisensory interaction, intraoral interfaces, electrotactile stimulation, sensing, and virtual and mixed reality.
I received my M.Eng. in Informatics from the University of Electro-Communications (UEC) in March 2026. My research explored how electrical stimulation inside the mouth can evoke tactile sensations and influence food texture perception.
During a research internship at the University of Chicago, I also worked on electrical stimulation of the nasal trigeminal system.
