I love to share the excitement and joy of mathematics with others. Making mathematics visual allows a large audience to experience beauty in conjunction with mathematics, as I do. My goal is to create objects that both display a mathematical concept and intricately use mathematics in their creation.

Temari (stitched thread balls: styrofoam, yarn, thread, and perle cotton)
2022
Temari is a traditional Japanese needlecraft consisting of embroidery into a thread wrapped spherical. For the Mathemalchemy art installation project, I proposed that we depict the Catalan solids on selected temari balls and devised three interwoven stitching plans for the dispersed group of stitchers. This thirteen ball set is a cross-section of a larger in-progress piece consisting of my solo stitching of the thirty-nine temari balls depicting each of thirteen spherical Catalan solids stitched with the three different interwoven stitching plans. The two enantiomorphic solids (pentagonal icositetrahedron and pentagonal hexecontahedron) are stitched with a face outlining plan. The other eleven employ an edge outlining plan.
