Will Sawin

William French Sawin (born in October 1993) is the Fernholz Professor of Mathematics at Princeton University specialising in number theory and algebraic geometry.

Early life and education Will Sawin was born in Malden, Massachusetts in October 1993. He was a child prodigy and began his undergraduate studies at Yale University when he was 10 years old.

Career Sawin was a postdoctoral junior fellow at ETH Zürich from 2016 to 2018. He moved to Princeton University as a professor of mathematics in 2024.

Research Sawin found important applications of étale cohomology to the theory of exponential sums over finite fields. He also uses classical counting techniques in analytic number theory in the study of cohomology of spaces that are of interest in algebraic geometry. In 2023, Sawin was awarded a Sloan Fellowship.
