Philip Ording is a writer and mathematician. He is interested in formal problems that surface in the arts and the expressive resources that their unraveling offers mathematics. Since 2003 he has worked as a mathematics consultant in art and architecture studios in New York. His book, 99 Variations on a Proof, which is based on the literary experiments of the Paris-based group of writers known as the OuLiPo, was published by Princeton University Press in 2019 and received the 2020 PROSE Award for Excellence in Physical Sciences and Mathematics. His writing has also appeared in Cabinet, The Serving Library and exhibition catalogs published by Steidl/David Zwirner and Hatje Cantz. He holds a PhD from Columbia University and teaches mathematics at Sarah Lawrence College, where he is pursuing an MFA in creative nonfiction.
