Guillaume Cassabois, winner of the SFP’s 2025 Jean Ricard Grand Prize

Congratulations to Guillaume Cassabois (Professor at the University of Montpellier), winner of the 2025 Jean Ricard Grand Prize awarded by the French Physical Society

A professor and researcher at the Charles Coulomb Laboratory and a senior member of the Institut Universitaire de France, he is being honored for his major contributions to semiconductor photonics.

His work has made significant contributions to several key fields:
=> Quantum dots and exciton decoherence
=> Boron nitride (BN) photonics
=> Defect-based quantum emitters in silicon

At the intersection of fundamental physics and quantum technologies, Guillaume Cassabois is now a leading international figure.
