Chiara Coletti graduated in 2010 in Science and Technology for Archaeological and Artistic Heritage and held the PhD in 2016 in Earth Science. Her research interests mainly include the characterization of natural and artificial rocks applied in built heritage, the radon occurrence, and archaeometry. Since 2022 she has been a researcher at the University of Padua, Department of Geosciences, with a fellowship funded by PNRR Young Researchers – Seal of Excellence (SoE). Her research project, M3DEA, aims to help answer the general question “how to preserve cultural identity referring to future climate conditions?”. The Diagnostic Imaging Model (DIM) for the quantification of stone cultural heritage deterioration will be based on the study and comparison of high-resolution 3D models obtained from the original monument (the Trajan’s Column, 113 A.D., Italy) with those achieved from its historical replicas (with known dates of production, e.g. 1666-1667, 1861-1862) and photographic material from its last major restoration works (in the 1980s and '90s). The bas-reliefs of the Trajan’s column are characterized by a complex decoration and a large number of details hence its meaningfulness in defining standards for a 3D morphometrical/geometrical analysis to be applied in a broader cultural heritage patrimony in support to local authorities in historical urban planning.
