Florence’s current research is largely devoted to remote spectral imaging and sensing as well as data science for the analysis of a broad range of cultural heritage, including murals and architectural interiors, degraded ancient bronze, historical cartographic collections and carbonised papyri.
Research in data science includes development of machine-learning methods for large scale data reduction and material mapping; interactive graphical database for large scale historical genealogical data, and more recently 3D data visualisation of spectral imaging datasets and material maps for scientific and outreach purposes.
Previous work also has its applications in industry and involves development of an adapted airborne imaging system, and methods in outdoors spectral imaging calibration, for the large scale mapping of metal degradation.
