Romain GRANGEAT

Romain GRANGEAT serves as a Teacher-researcher at CESI's Le Paquebot Campus in Saint Nazaire, France, where he contributes to the Engineering and Digital Tools research team. His dual role bridges academic instruction for engineering students with experimental research focused on material durability and advanced sensing methodologies.

His academic foundation includes:

• Doctorate from Nantes University investigating 'Durability of bonded assemblies in humid environments – Instrumentation by fiber optic sensors'
• Engineering Diploma from INSA Rennes specializing in 'Materials Science and Engineering'

Dr. GRANGEAT's research program centers on material degradation mechanisms in organic systems, particularly epoxy-based adhesives. He pioneers fiber optic sensing techniques to quantify water diffusion dynamics at microscopic scales within bonded assemblies. His work integrates physicochemical characterization with mechanical analysis to address real-world challenges in structural adhesion across aerospace, automotive, and marine sectors, emphasizing the critical role of interphase properties in long-term performance.

Analysis of his 2019-2023 publications reveals a cohesive research trajectory focused on moisture-induced degradation in epoxy/metal interfaces. His group consistently develops and refines Fresnel reflection-based sensing methodologies to map local water content fields with unprecedented spatial resolution. This work establishes fundamental relationships between environmental exposure, interphase evolution, and mechanical failure, providing industry with predictive models for bonded assembly lifetime under humid conditions.

Scientific awards and honors: None documented in available source materials.

Dr. GRANGEAT actively mentors doctoral candidates, currently co-supervising E. Pinto's thesis at CEFET/RJ (Rio de Janeiro) since September 2023. The research investigates 'The influence of hygroscopic aging on the creep of bonded joints,' addressing critical knowledge gaps in time-dependent adhesive behavior. While specific grant funding isn't detailed in available materials, his research demonstrates strong industry alignment through its focus on practical durability solutions for structural bonding applications.

He operates within CESI's Engineering and Digital Tools research ecosystem, which combines experimental mechanics laboratories with digital instrumentation development to advance sustainable material solutions for engineering applications.
