Education and careerEdit

Pipher is currently the Elisha Benjamin Andrews Professor of Mathematics at Brown University. She received a B.A. from the University of California, Los Angeles in 1979 and a Ph.D. from UCLA in 1985 under the direction of John B. Garnett.[3] She taught at the University of Chicago (1985–1990) before taking a position at Brown in 1990, where she served as chair of the Mathematics Department from 2005 to 2008.

In 1996, Pipher, along with Jeffrey Hoffstein, Daniel Lieman and Joseph Silverman, founded NTRU Cryptosystems, Inc. to market their cryptographic algorithms, NTRUEncrypt and NTRUSign.


In 2012 she became a fellow of the American Mathematical Society.[4] In 2017, she was selected as a fellow of the Association for Women in Mathematics in the inaugural class.[5] In 2019 she was named a SIAM Fellow "for her profound contributions in analysis and partial differential equations, groundbreaking work in public key cryptography, and outstanding scientific leadership".[6]

n 2014 Pipher was a Mathematical Association of America Invited Lecturer at the Joint Mathematics Meetings, speaking on The Mathematics of Lattice-based Cryptography[7] The Association for Women in Mathematics named her as their Noether Lecturer for 2018.[8]

In 2017, she was elected to a two-year term as president of the American Mathematical Society, to begin in 2019.[9]
