CNRS Crystal Medal 2025

Computer networks and systems

A research engineer at the Institut de Mathématiques de Bordeaux, Sandrine Layrisse plays a key role in the organisation and management of computer engineering dedicated to mathematics. In particular, she is director of the Mathrice thematic network, which provides tools for the entire French mathematics community through the online platform for mathematics, which will be awarded the collective Crystal Medal in 2021. Sandrine Layrisse is working on the national structuring of digital services in mathematics, while coordinating the work of around twenty people. Her career has been marked by strong involvement in collective projects, illustrating her constant commitment to local IT that is consistent with the needs of laboratories. She is currently taking part in the European EOSC LUMEN project, while passing on her know-how to new generations of network experts.

The National Institute of Standards and Technology (NIST) has just made official the standardization of the HQC (Hamming Quasi-Cyclic) algorithm, the fruit of collaboration between the XLIM laboratory (University of Limoges / CNRS) and the Mathematical Institut of Bordeaux (CNRS / University of Bordeaux / Bordeaux INP). This post-quantum encryption, based on error-correcting codes, is becoming one of the new international standards in digital security, alongside the ML-KEM algorithm. It will help protect digital exchanges against future threats posed by quantum computing.

Congratulations to Gilles Zémor and his colleagues in the XLIM laboratory on this outstanding achievement!

The Society for Industrial and Applied Mathematics (SIAM) has announced the 2025 recipients of its major prizes and awards.

The 2025 W. T. and Idalia Reid Prize is awarded to Marius Tucsnak for his fundamental work on the mathematical analysis and control of fluid-structure interaction and for his deep contributions to control theory and partial differential equations. This prize will be awarded at SIAM AN25 with an associated lecture.

Congratulations to Marius for this well-deserved achievement!
