grew up in the Bronx and studied at the Fashion Institute of Technology, as well as the School of Visual Arts, New York. She works in sculpture, drawing, photography and printmaking. Gellis' public art projects deal with environmental issues. In a conceptual landscape piece from 1992, she collected 150 samples of soil from different places around the world (Morocco, Greece, Iceland, Egypt ) and arranged them in a cartographic grid on the wall in a gallery space. Another project dedicated to the Hudson River consisted of a combined photographic record as well as samples of soil collected from the Hudson River near Lower Manhattan. In her work, Gellis places us in a context of something natural and temporary. She combines water, oxygen and minerals and utilizes them as metaphors for natural processes.
