The list of winners of the CNRS 2025 medals was unveiled on June 16, 2025. Three members of ENS de Lyon are among them! They are Gwyneth Ingram, CNRS researcher and director of the Plant Reproduction and Development laboratory (silver medal); Benjamin Wesolowski, CNRS research fellow at the Center for Pure and Applied Mathematics (bronze medal); and Stéphanie Durand, CNRS researcher and seismologist at the LGL-TPE (bronze medal). Alumni of ENS de Lyon are also among the distinguished scientists.
Every year since 1954, the CNRS has honored members of the French scientific community with awards that recognize the excellence of their work and their contribution to the advancement of research, its influence and the advancement of knowledge in the many specialties covered by science. For the 2025 edition, the CNRS has awarded 24 silver medals, 46 bronze medals and 34 crystal medals. Among the winners are three members of ENS de Lyon, whom we invite you to discover here.

Gwyneth Ingram, CNRS Silver Medal
CNRS Research Director and Director of the Reproduction and Development of Plants Laboratory (CNRS/ENS de Lyon/Inrae), Gwyneth Ingram studies how the different tissue compartments of the seed communicate to form a coherent structure. She has been awarded the CNRS silver medal.
Two ENS de Lyon alumni have also received the CNRS silver medal:
- Cécile Cottin-Bizonne, CNRS research director at the Institut Lumière Matière (iLM, CNRS/Université Claude Bernard Lyon 1),
- Serge Cantat, Research Director at the Institut de Recherche Mathématiques de Rennes (IRMAR).
Benjamin Wesolowski, CNRS bronze medal
Benjamin Wesolowski is a CNRS research fellow at UMPA, Unité de mathématiques pures et appliquées (CNRS / ENS de Lyon), who explores the mathematical foundations of post-quantum cryptology. A specialist in cryptology based on number theory and algebraic geometry, he is helping to develop new security systems capable of withstanding quantum computing.


Stéphanie Durand, CNRS bronze medal
Stéphanie Durand is a CNRS research fellow at the Laboratoire de géologie de Lyon : Terre, planètes, environnement (LGL TPE, CNRS/Université Claude Bernard Lyon 1/ENS de Lyon). A specialist in the earth's mantle, she works on innovative seismic imaging techniques, from the speed of propagation of seismic waves to the way they are attenuated by the medium they pass through.
Five ENS de Lyon alumni have also received the CNRS bronze medal:
- Dante Fedele, CNRS research fellow, legal historian specializing in the study of modern diplomacy and international law at the Centre d'histoire judiciaire (CNRS / Université de Lille),
- Nicolas Martin, CNRS research fellow at the Paul Pascal Research Center (CRPP1),
- Romy Sanchez, historian specializing in the imperial history of migration and exile between Europe and Latin America,
- Myriam Suchet, lecturer in French and Francophone languages and literature, director of the Centre d'études québécoises de Paris 3,
- Sébastien Tavenas, CNRS research fellow at the Laboratoire d'analyse et de mathématiques appliquées (LAMA - CNRS/Université de Savoie Mont Blanc).
