Mathematician Stéphane Mallat receives the CNRS Gold Medal

Stéphane Mallat's work is internationally recognized in the field of mathematics for signal processing and statistical learning. He is notably the inventor of an algorithm that forms the basis of the JPEG 2000 image compression standard, and he laid the mathematical foundations for deep learning models at the heart of modern artificial intelligence.

A former student of École Polytechnique (X81), he obtained a PhD from the University of Pennsylvania in 1988. He was a professor in the Department of Applied Mathematics at École Polytechnique from 1995 to 2012, serving as department chair from 1998 to 2001. Stéphane Mallat currently holds the Chair of Data Science at the Collège de France.  

Created in 1954, the CNRS Gold Medal recognizes scientific careers that have made an exceptional contribution to the dynamism and influence of French research. It will be awarded to Stéphane Mallat on December 17, 2025, during a ceremony in Paris.
