sarah-marie belcastro
I’m a math professor by trade, and (unsurprisingly) my designs are informed by mathematical concepts. I co-edited the books Making Mathematics with Needlework: Ten Papers and Ten Projects and Crafting by Concepts: Fiber Arts and Mathematics with my colleague and friend Carolyn Yackel. You can find out more than you ever wanted to know about me and my way-too-many interests (including my ex-cat, socially responsible investing, dance, feminist philosophy of science,…) at my domain www.toroidalsnark.net.
I also co-design with MadStuart as the design team sarah-marie belcastro and Madison Stuart under the name Knits with a Side of Math.
