Cecelia Campochiaro started knitting at age twelve as a hobby. She has a doctorate in physical chemistry and has lived and worked in Silicon Valley for more than twenty years, developing different kinds of microscopes for finding problems with computer chips. Cecelia began experimenting with new ways to create fabric when flying on business trips. These ideas grew, and eventually the book Sequence Knitting was born. Textiles, photography, and the arts have been lifelong passions, and she loves thinking about how these different creative areas intersect with math and science.
