Research Activity

My expertise in neutron scattering ranges from spin-echo (NSE), through quasi-elastic (QENS) and inelastic (INS), up to deep-inelastic (DINS) timescales. Broadband dielectric relaxometry (BDR) and high-resolution nuclear magnetic resonance (NMR) complete the picture. Special focus on dynamic, structural, and energetic characterization of soft matter systems â especially condensed phases of bulk and confined water.
Currently in charge of a full-energy-peak (FEP) efficiency calibration of an n-type coaxial HPGe detector used for quantitative (n, gamma) spectroscopy on Cultural Heritage multicomponent manufacts and quantitative estimates of the absolute gamma background at various beamlines located at ISIS neutron source. The task includes the experimental part, together with the reconfiguration of the IT resources available in the SWING lab (re-design of a medium-size Linux-based parallel CPU cluster) in order to implement complementary Monte Carlo simulations of the FEP efficiency by Geant4 code.
Currently completing a specialized training in Radiation Protection, which is preparatory to the national examination as a 1st-grade Qualified Expert in ionizing radiation.
