Francis Michael Christ (born 7 June 1955) is an American mathematician and professor at University of California, Berkeley, specializing in harmonic analysis, partial differential equations, and several complex variables.

He received in 1977 from Harvey Mudd College his bachelor's degree[1] and in 1982 from the University of Chicago his PhD under the supervision of Alberto Calderón with thesis Restrictions of the Fourier transform to submanifolds of low codimension.

[3] At Princeton University, Christ worked with Elias M. Stein from 1982 to 1984 as an instructor and from 1984 to 1986 as an assistant professor.

He was an invited speaker of the International Congress of Mathematicians in 1990 in Kyoto[4] and in 1998 in Berlin.

[2] He was named to the 2021 class of fellows of the American Mathematical Society "for contributions to harmonic and complex analysis, and linear partial differential equations".
