In his work, Bohyun Yoon explores the conceptual properties of glass more than the actual, physical glass itself. He searches for ways to visualize its transparency, often experimenting with other materials to do so. He currently is expanding his study of visibility and perception by researching the illusion of human relationships. His work is in the permanent collections of the Smithsonian American Art Museum, West Collection, Tama Art University and Song Eun Art Space.
