Contributions

With Richard F. Riesenfeld and Gershon Elber, Cohen is the author of the book ''Geometric Modeling with Splines: An Introduction'' (AK Peters, 2001). She has also contributed to the development of the Utah teapot, improving it from a two-dimensional surface with no thickness to a bona-fide three-dimensional object.
