Physicist at the particle physics division of CEA, Saclay, France 

CEA/IRFU/SPP, Bâtiment 141, 91191 Gif-sur-Yvette


Research Interests

I have been involved mainly in three fields in astroparticle physics: (i) neutrinoless double beta decay (2004 – today), (ii) direct search for dark matter (2007 – today) and (iii) axion physics (2012 – today). In this activity I had the opportunity to develop several multidisciplinary skills:
• Design, fabrication and operation of low temperature detectors for astroparticle physics
• Thermometry at very low temperatures
• Cryogenics, also at dilution-refrigerator temperatures (<20 mK)
• Analysis and interpretation of background radioactivity spectra
• Measurements of low-level signals at low noise
• Basic neutrino properties
• Cold dark matter candidates
• Axion models and their relevance in astrophysics and cosmology

I'm involved in the following projects :
