## About

Kristin Lauter is a Principal Researcher and Research Manager for the Cryptography group at Microsoft Research. Her research areas are number theory and algebraic geometry, with applications to cryptography. She is particularly known for her work on homomorphic encryption, elliptic curve cryptography, and for introducing supersingular isogeny graphs as a hard problem into cryptography. She served as President of the Association for Women in Mathematics from 2015 –2017.

Lauter was elected to the 2015 Class of Fellows of the American Mathematical Society “for contributions to arithmetic geometry and cryptography as well as service to the community.” In 2017, she was selected as a Fellow of the Association for Women in Mathematics in the inaugural class. She was selected as the Polya Lecturer for the Mathematical Association of America for 2018-2020. In 2008, Lauter and her coauthors were awarded the Selfridge Prize in Computational Number Theory.

She is a co-founder of the Women in Numbers Network, a research collaboration community for women in number theory, and she is the lead PI for the AWM NSF Advance Grant (2015-2020) to create and sustain research networks for women in all areas of mathematics. She is the Series Editor for the AWM Springer Series. She serves on the Advisory Board[6] of the Banff International Research Station, the Board of Trustees of MSRI, and has served on the Council[7] of the American Mathematical Society (2014-2017).

Lauter received her BA, MS, and Ph.D degrees in mathematics from the University of Chicago, in 1990, 1991, and 1996, respectively. Prior to joining Microsoft, she held positions as a Visiting Scholar at Max Planck Institut fur Mathematik in Bonn, Germany (1997), T.H. Hildebrandt Research Assistant Professor at the University of Michigan (1996-1999), and a Visiting Researcher at Institut de Mathematiques Luminy in France (1999).
