Casey Mann is an American mathematician, specializing in discrete and computational geometry, in particular tessellation and knot theory.
He is known for his 2015 discovery, with Jennifer McLoud-Mann and undergraduate student David Von Derau, of the 15th and last class of convex pentagons to tile the plane.
His dissertation in discrete geometry, supervised by Chaim Goodman-Strauss, was Heesch's Problem and Other Tiling Problems.
[9] Upon completing his doctorate, Mann joined the University of Texas at Tyler faculty for eleven years.[2].
He joined the faculty of University of Washington Bothell in 2013, where he is active in engaging undergraduate students in research.
