Christine Bachoc (born 1964) is a French mathematician known for her work in coding theory, kissing numbers, lattice theory, and semidefinite programming. She is a professor of mathematics at the University of Bordeaux.
Bachoc earned a doctorate in 1989 with the dissertation Réseaux unimodulaires et problèmes de plongement liés àla forme Trace.
In 2011, Bachoc and Frank Vallentin won the Society for Industrial and Applied Mathematics Activity Group on Optimization Prize for their work proving upper bounds on high-dimensional kissing numbers by combining methods from semidefinite programming, harmonic analysis, and invariant theory.
