Hi. I’m Jeesun Oh, UX/HCI Researcher.

I am studying human-AI interaction, with a Ph.D. in Industrial Design from KAIST and a current position as a Visiting Professor at Yonsei University in South Korea.

My research focuses on how people communicate with conversational AI, including embodied AI such as robots, wearables, and smart appliances, and how they come to perceive these systems as social presences across diverse service contexts. For more about my background, please see my about section.
