His research interests are 3-manifolds and triangulations, hyperbolic geometry, and mathematical visualisation and 3D printing. He authored the book \u003Cem\u003EVisualizing Mathematics with 3D Printing,\u0026nbsp;\u003C\/em\u003Epublished in September 2016 by Johns Hopkins University Press. This mathematics book is intended for a popular audience, with the twist that most of the figures in the book are photographs of 3D-printed models. These models are available for readers to download and 3D print themselves, or order online, or explore virtually on the book\u0026#39;s website, \u003Ca href=\u0022http:\/\/3dprintmath.com\/\u0022\u003E3dprintmath.com\u003C\/a\u003E.
