Marie Semeria became CEO of Leti in October 2014. She also was named president of the Carnot institutes network, an association of more than 30 French research centers and laboratories.

During her previous 18 years at CEA, she held a variety of senior-management and strategy-development positions, and helped secure numerous patents.

During that time, she also took on the additional responsibility of deputy director in charge of strategy, working closely with the Carnot institutes network.
