Christopher Hanusa is a Professor of Mathematics and mathematical artist based in New York City. Inspired by the beauty of mathematics, he started Hanusa Design Mathematical Jewelry in which every piece is 3D modeled using mathematical equations in a computer and then 3D printed in nylon or in metal through a lost wax casting process. The nylon pieces are subsequently dyed in a variety of bright colors. His pieces can be found in the National Museum of Mathematics, the Queens Museum, and the Exploratorium in San Francisco. The “Riemondrian Collection,” a collaboration between Hanusa and origami artist Uyen Nguyen, appeared at the 2019 Bridges Fashion Show in Linz, Austria.
