Julien THEBAULT

Julien THEBAULT is a Lecturer in Marine Biology and Ecology at the University of Western Brittany, affiliated with the LEMAR Laboratory. His research focuses on sclerochronology and the geochemical analysis of mollusk shells to reconstruct past environmental conditions in coastal ecosystems.

• Doctorate in Biological Oceanography (2005)
• Accreditation to Supervise Research (2019)
• Master’s in Biology of Marine Populations (2000)
• DEUG in Life Sciences (1998)

He specializes in using mollusk shell proxies to study environmental variability (temperature, salinity, pollution) and ecological functioning across temperate, tropical, and polar coastal systems. His work combines geochemical techniques like laser ablation and mass spectrometry with ecological modeling.

Julien is a certified scientific diver with the Certificat d’Aptitude à l’Hyperbarie and advanced rebreather certifications. Collaborators include Prof. Melita Peharda (Croatia) and Prof. Bernd R. Schöne (Germany).
