After his PhD thesis in Nuclear Magnetic Resonance and Muon Spin Resonance on orbitally ordered compounds at the University of Parma, Claudio moved to X-rays science at the European Synchrotron Radiation Source (ESRF) in Grenoble.
There he worked at the magnetic scattering beamline (ID20) acquiring specific experience on Resonant X-ray Diffraction (RXD).
Claudio performed experiments in X-ray diffraction and absorption at the major synchrotron sources around the World, complementing his scientific activity with neutron experiments on both powders and single crystals.
Once back to the Italian university, he complemented diffraction investigation of strongly correlated systems with X-ray spectroscopy, mainly by RIXS (Resonant Inelastic X-ray Scattering) in the soft energy regime.
Claudio moved to NSLS-II at the end of 2014, as a beamline scientist on 23-ID-1, CSX (Coherent Soft X-ray scattering).
Currently, he is the Lead Beamline Scientists of CSX.

Research Highlights

? understanding of electronic mechanisms in some manganites multiferroics and magnetoelectrics;
? discovery of new phases and electronic couplings in frustrated low dimensional magnets (partially disordered anti-ferromagnetic structures);
? first observation of charge density wave (CDW) phases and its relation with superconductivity in series of cuprate high temperature superconductors;
? development of new complementary techniques for resonant experiments, relying on full polarization control on tensorial scattering, particularly useful in demanding sample environments and micro domain samples;
? high electric field setup for in-operando investigation of piezoelectric materials and quantum paraelectrics by X-ray diffraction.
