RESEARCH INTERESTS:
My research activity is in the field of fundamental interactions and experimental high energy physics. After a contribution to the R&D and test beam of ATLAS monitored drift tubes (MDT) detectors for the Atlas muon spectrometer in 1998 and 1999, I joined the CDF collaboration at Fermilab before the start of Tevatron collider Run 2 in 2000. My research in CDF was focused on flavor physics and CP violation in charm and beauty hadrons. I gave a strong contribution to the observation of Bs meson flavor oscillations and served as conveener of the “Rare B decays and CP violation” CDF physics group. In 2008 I re-joined the ATLAS experiment at LHC with the LPNHE Paris group and contributed significantly to the Higgs boson discovery in the di-photon decay channel, in Higgs vector boson fusion production mechanism evidence, in ATLAS photon trigger and reconstruction performances and in ATLAS detector operations during LHC Run 1. Since 2013, I worked on the search for the yet unobserved Higgs boson decay to b quarks in the production in association with gauge bosons, on the missing energy significance reconstruction and more recently, on the search for dark matter production at LHC in the mono-Higgs signature with Higgs decaying to b quark pairs with missing energy. At the end of 2014 I joined the DARKSIDE collaboration for the dark matter direct search with liquid argon double phase TPC at LNGS. Within the DARKSIDE collaboration I am involved in both the physics analysis of the current DarkSide-50 experiment and in the design, R&D and construction of the future DarkSide-20k 20-ton fiducial liquid argon detector.
