In 1988, Hart began to exhibit with the Pat Hearn Gallery, moving from critical to artistic practice. At that time, she exhibited paintings and installations inspired by the visionary architectural languages of Ledoux, Boullee and Leque. After receiving an NEA Fellowship in 1989, she moved her practice to Europe where she spent ten years and received numerous fellowships, including the Kunstfond Bonn, Stiftung Kulturfonds, the Stiftung Luftbrueckendank Grant, the Arts International Foundation Grant, the Kunstlerhaus Bethanian grant, two fellowships from the American Center in Paris, and an honorary fellowship at Eyebeam.
