Sarah Gelsinger Brewer is an artist-mathematician from Mobile, Alabama, USA. She is interested in the mathematical tools for making art, the inherent beauty in pure mathematics, and the application of artistic and mathematical methods to other disciplines.

Her current body of artistic and mathematical work is an investigation into classical Islamic geometric designs, paying particular attention to the circle packing that arises organically from the underlying Euclidean compass and straightedge construction. She also enjoys artistic and mathematical problems in origami, knot theory, perspective drawing, and data visualization.

She is available for workshops and commissions. For tutorials on the digital construction of Islamic geometric patterns using GeoGebra, support her on Patreon for as little as $1/month.
