Guillaume J.A. Bresso specializes in the authentication, dating, and provenance research of artworks from Maya, Olmec, Mixtec, Teotihuacan, Chupícuaro, and Colima cultures. His methodology combines close iconographic and stylistic analysis with a deep knowledge of ancient techniques and scientific methods — including thermoluminescence, mass spectrometry, and anthracology — carried out in collaboration with leading laboratories.
This integrated approach allows for conclusions grounded in multiple lines of evidence, always respecting the highest standards of international due diligence and compliance.
