Born in Seoul, South Korea, Koo Jeong A studied at the École nationale supérieure des beaux-arts in Paris. She gained international recognition in the 1990s for her minimalist installations that often incorporate found objects and subtle interventions within gallery spaces.

Her practice spans a diverse range of media, including drawing, film, photography, and large-scale architectural installations. She is particularly noted for her interest in the sensory experience of environments, frequently employing elements like phosphorescent paint or olfactory components to engage the audience beyond the visual.

Koo has exhibited extensively at major international institutions and biennials. Her work continues to be recognized for its ephemeral quality and its ability to transform mundane surroundings into contemplative, atmospheric experiences.
