RESEARCH LINES  
 

My scientific path is characterized by a highly multidisciplinary approach, which covers the areas of physical, chemical sciences applied to the conservation of Cultural Heritage. My main research interests and experiences are:

 

Raman spectroscopy:

Development of a new Raman method (micro-SORS) for the non-invasive subsurface investigation of Cultural Heritage materials; the method enables to recover the chemical composition of deep layers noninvasively. Micro-SORS has a strong potential impact in conservation field as well as in materials science and biomedical sectors.

Application of FT-RAMAN, µRaman and µRaman mapping are explored for the compositional characterization of Cultural Heritage materials and their decay, to asses the efficacy of conservation treatments, to investigate the mechanisms of formation and transformation of crystalline phases formed after conservation treatments.

 

Inorganic mineral products for conservation:

Study of physical and chemical transformations occurring in the inner portions of materials treated with conservation products: the main research line concerns the optimization of new methods to assess the distribution and penetration depth of inorganic treatments.

Study of the diffusion of conservation products through neutron sources.

  

Non-invasive instruments and methods:

Critical evaluation of the analytical performance of noninvasive techniques used in Conservation Science. An extensive range of portable instruments is interrogated such as X-Ray fluorescence, optical microscopy, IR and Raman spectroscopy, spectrophotometry (VIS).
