Sangjun Yoo is an artist and researcher whose work examines how perception is shaped through time, environment, and technological systems. His practice emerged from doctoral research focused on perceptual mediation and has since expanded into installation-based and moving-image works that engage viewers through evolving relationships between human attention, computational processes, and environmental signals.

Working with multi-channel video, spatial sound, environmental data, and custom computational frameworks, Yoo investigates perception as an active, relational event rather than a fixed response. His recent work brings perceptual theory and systems thinking into dialogue with digital and computational media, exploring how awareness, memory, and orientation shift within distributed and responsive environments that unfold over time.

Yoo holds a Ph.D. in Digital Media and Experimental Arts from the University of Washington.
