Frank Calegari, Professor and Associate Chair of Mathematics, has been named a 2026 Simons Fellow in Mathematics. The Simons Fellows Program provides funds to faculty for up to a semester-long research leave from classroom teaching and administrative obligations.
“Sabbatical research leaves provide mathematicians with opportunities for intellectual stimulation and collaboration that foster innovative research,” says the Simons Foundation website. The foundation’s Mathematics & Physical Sciences division provides funding to make sabbatical or equivalent research leaves more productive by extending them from a single term to a full academic year.
Calegari’s research is in the area of algebraic number theory. He is particularly interested in the Langlands program, a set of mathematical ideas that has been called the "grand unified theory of mathematics.” He is also interested in the cohomology of arithmetic groups, especially in torsion classes.
