Hello, I am Heejeong Ko, a Ph.D student at the KAIST UVR Lab under the supervision of Prof. Woontack Woo.

My research investigates how embodied virtual agents should express themselves in Mixed Reality. I focus on adaptive embodied actions—gestures, demonstrations, and persona-driven behaviors—that respond to the user's context, aiming to create MR environments where virtual agents act as spatially aware, socially engaging partners.
