Dion is known for making art out of fieldwork, incorporating elements of biology, archaeology, ethnography, and the history of science, and applying to his artwork methodologies generally used for pure science. Traveling the world and collaborating with a wide range of scientists, artists, and museums, Dion has excavated ancient and modern artifacts from the banks of the Thames in London, established a marine life laboratory using specimens from New York’s Chinatown, and created a contemporary cabinet of curiosities exploring natural and philosophical hierarchies. His approach emphasizes illustration and accuracy but is charged with a biting undertone. Dion has a longstanding interest in exploring how ideas about natural history are visualized and how they circulate in society. Dion’s work has been presented at many U.S. and international museums and galleries, including solo exhibitions at the Vancouver Art Gallery, Vancouver; Galleria Emi Fontana, Milan; Wexner Center for the Arts, Columbus, Ohio; Tanya Bonakdar Gallery, New York; and Deutsches Museum, Bonn. Dion has been commissioned to create works for Aldrich Museum of Art, Ridgefield, Connecticut; the Tate Gallery, London; the Yerba Buena Center for the Arts, San Francisco; and The Museum of Modern Art, New York.
