Kristin Estella Lauter (born 1969)[1] is an American mathematician and cryptographer whose research interest is broadly in application of number theory and algebraic geometry in cryptography.

Prior to joining Microsoft, she held positions as a visiting scholar at Max Planck Institut fur Mathematik in Bonn, Germany (1997), T.H.

[7] Dr. Kristin Lauter is also known for her work in homomorphic encryption, which has been commonly used in machine-learning, building mathematical models, private AI, and the collection of genomic data.

[8] Beginning in April 2021, Lauter joined Facebook AI Research as West Coast Head of Research Science, leading the Seattle and Menlo Park Labs with groups in Core Machine Learning, Computer Vision, Robotics, Natural Language Processing, and other areas.

[15] Lauter and her coauthors were awarded the Selfridge Prize at ANTS VIII for their paper Computing Hilbert Class Polynomials.

[16] She 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.
