Research Topics

My research tries to bridge the most recent knowledge achieved on the study of the materials at the nanometric - and possibly atomic - scale and the study of materials from the cultural heritage. Ancient ceramics are complex systems that need advanced techniques to investigate their structure and microstructure. I study the multi-scale features of ancient ceramics by spectral imaging collected using synchrotron radiation. These techniques can be used to better understand the operating conditions employed during the artifact’s manufacturing, the actual preservation state and the mechanisms at the basis of such material modification.

Currents research

  • Study of the fossilized microstructure of the corroded copper-based ancient amulet of Mehrgarh (4000 b.C) by coupling different spectroscopic techniques and in particular high-resolution transmission electron microscopy (HR-TEM) and photoluminescence spectroscopy.
  • Study of the chemical speciation of the pigments contained in the glaze of ancient Chinese porcelains, from the Tang to the Ming dynasty, by X-ray absorption spectroscopy.
  • Collaboration with the beamline PUMA for the commissioning of the Full Field X-ray Absorption Near Edge Spectroscopy (FF-XANES) technique.


Master Degree in Materials Engineering at the Università degli Studi di Padova (2014). During my master thesis internship, I worked on the preparation of biopolymer-based magnetic composite containing magnetic nanoparticles for biomedical applications. I continued to study the behavior of magnetic nanocomposite materials during my PhD research project at the ITODYS laboratory of Paris Diderot University. I focused on the synthesis, sintering and characterization of oxide-based nanoparticles. In particular, I used analytical techniques such as Focused Ion Beam for sample preparation, HR-TEM, scanning electron microscopy, X-ray Diffraction analysis and magnetic analysis (Vibrating Sample Magnetometer and SQUID) to understand the structural and microstructural evolution of the nanoparticles after Spark Plasma Sintering. At the begin of 2018 I started a post-doctoral project at the IPANEMA laboratory, where I study the complexity of ancient ceramics structure at the atomic scale using different techniques, including techniques based on synchrotron radiation.
