Colleen Mulligan is originally from New York City. She attended Pratt Institute in New York City, from which she received her Bachelor of Fine Arts degree in 2002. While in college, Mulligan traveled to Europe to study art in the cities of Venice and Amsterdam. She has exhibited her work in the United States and in Europe. In 2005, Mulligan was accepted into the Florence Biennale, which featured honorary guest artists Christo and Jeanne-Claude.
In her work, Mulligan obscures reality, creating sexually charged images of folding flesh, intertwining into organic configurations. Morphing these images into imaginative bodies that evoke a sense of intimacy and at times uneasiness, she creates an experience for the viewer that is as complex and contradictory as a relationship itself.
