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 à la 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.
