Mathematician, artist, teacher, maker.
Edmund Harriss is an Assistant Professor in the department of Mathematical Sciences and the School of Art at the University of Arkansas, working between mathematics and art, especially in mathematical illustration.
Geometric Flows
Placeholder for project explaining geodeisc flow and continued fractions with Pierre Arnoux.
Curvahedra
A modular construction system to explore the geometry of curvature.
Algebraic Starscapes
The beautiful patterns that appear when algebraic numbers are plotted with sizes determined by complexity (such as functions of the discriminant), revealing geometric structure.
Zip-Form
A computation-and-fabrication system for creating curved architectural forms by zipping flat-cut pieces together. Developed with architect Emily Baker at the University of Arkansas, Zip-Form pairs mathematical formulations for parallel transport with a simple jig-based assembly process, enabling complex 3D curves from plasma-cut steel and basic tools. The work spans a permanent public sculpture, papers at AAG and IASS, and an ongoing collaboration on shape-optimised concrete formwork.
Illustrating Mathematics
Strengthening and making visible the role mathematical illustration has always played in mathematical discovery.
Tilings, substitutions and Projection
Research into the relationship between substitution rules and projection tilings.
Genuine Pretending
A philosophical framework for mathematical art developed with Roger Antonssen and drawn from Moeller and D'Ambrosio's reading of the Zhuangzi.
Patterns of the Universe
A mathematical coloring book co-authored with Alex Bellos.
Visions of the Universe
A mathematical coloring book co-authored with Alex Bellos.

Woven Permutation Rings
The rings my wife and I wear.
2D Crystals
Collaboration with physicist Salvador Barraza-Lopez applying discrete differential geometry to atom-thin crystalline materials. Especially how the geometry helps understand electric, optical and chemical properties.

Analysis of personal narratives from research mathematicians with dyslexia, exploring the strengths and challenges of neurodiverse mathematical thinkers.
Magnetic Klein Quartic
A physical model of the Klein quartic, a genus-3 hyperbolic surface tiled by 24 regular heptagonsmbuilt from neodymium magnets.
3D Spirographs
An exploration of spirograph curves extended into three dimensions, with Richard Grimes
