Ellen Kozak graduated from the Center for Advanced Visual Studies with Master of Science in Visual Studies in 1979, and was an early pioneer in video art. She was also a CAVS Fellow from 1979-1980. Since 1994, her work has focused more and more on the changing optical effects of the Hudson River through a daily practice of painting outdoors. She has had one previous solo exhibition at the Hudson River Museum, in 2001, and has shown more recently at Cross Contemporary Art, the Samuel Dorsky Museum of Art, and the Katonah Museum of Art. She has taught at Bennington College, Princeton University, and Pratt Institute.
