Christine Bachoc facts for kids
Christine Bachoc is a talented French mathematician born in 1964. She is a professor of mathematics at the University of Bordeaux in France. She is well-known for her important work in several areas of math, including how computers send information, how spheres can touch each other, and the study of special patterns.

What Does Christine Bachoc Study?
Christine Bachoc's research focuses on some really interesting parts of mathematics.
Coding Theory
One of her main areas is coding theory. This field of math helps us understand how to send information, like messages or videos, over long distances without errors. Think about how your phone sends a text message or how a satellite sends pictures back to Earth. Coding theory helps make sure those messages arrive correctly, even if there's some interference along the way.
Kissing Numbers
She also studies something called "kissing numbers." Imagine you have one ball, and you want to see how many other balls of the same size can touch it at the same time. That number is the kissing number! It sounds simple, but figuring this out in higher dimensions (more than the three we live in) is a very complex math problem.
Lattice Theory
Another area she works on is lattice theory. A lattice in math is like a perfectly organized pattern of points, repeating over and over. You can see examples of lattices in nature, like the way atoms are arranged in a crystal. Understanding these patterns helps in many areas, from designing better communication systems to understanding materials.
Semidefinite Programming
Christine Bachoc also uses a powerful math tool called semidefinite programming. This is a type of math that helps solve problems where you want to find the best possible solution, like finding the most efficient way to do something. It's used in many fields, from engineering to economics.
Her Education and Achievements
Christine Bachoc earned her doctorate degree in 1989. Her main research for this degree was about special types of patterns and how they fit together.
In 2011, Christine Bachoc and her colleague Frank Vallentin won a special award called the Society for Industrial and Applied Mathematics Activity Group on Optimization Prize. They won this prize for their amazing work on kissing numbers. They found new ways to figure out the maximum number of spheres that can touch a central sphere in very high dimensions. They did this by combining different math techniques, including semidefinite programming. Their work helped solve a long-standing puzzle in mathematics!
