Ellen Jong’s practice is rooted in conceptual performance and autobiographical themes. Jong is perhaps known best for her first major series, the infamous “Pees on Earth” photographs (1997-2005), featuring the artist urinating in a variety of public settings in the “pursuit of owning territory, body, rebellious antics, and the un-ownable.” Her subsequent photographic series feature scenes from her everyday life, including her surroundings, her marriage, and the intimacies of her husband’s body. She is also known for a body of sculptures made from rope knots, presented, as she describes, as “nodules in space” based on the idea of the Ouroboros—a serpent eating its own tail. Her latest work is developed around an autobiographical mythical character Wan Pi (Wánpí) whose first rendition is a life size running water fountain sculpture of Jong squatting and urinating. Cast from her own body, the character is named for the Chinese phrase that means "naughty" in English. Jong’s works in photography and sculptural installation also have become the subject of a number of her artist’s books.
