I firstly ultimated the analysis started in my master thesis, using data collected by the CMS Experiment at CERN in 2016, performing the statistical analysis in order to extract the final result. This was reported in a paper published on JHEP in November 2017 (DOI: 10.1007/JHEP11(2017)047). I presented these results in a talk I gave at the IFAE conference in Milano in April 2018. Then I focused my analysis on Higgs boson properties using data collected in 2017, performing a study on energy scale and resolution sistematics in order to update them in the analysis. The results obtained were reported in a Public note of the CMS Collaboration (HIG-18-001) published in June 2018. Recently I started working on the Higgs to 4 lepton analysis using 2018 CMS data, which are currently being collected by CMS. In parallel I recently started a different analysis focused on the searches of double Higgs boson looking at the bbZZ decay channel. This analysis will be completed using the full dataset collected by the CMS experiment in the LHC Run II (years 2016-2017-2018). In parallel to the analysis works I took part in the CMS data taking by covering shifts during July and August 2018 as on-call expert of the Drift Tubes muon detectors of the CMS Experiment. In August I took part in a INFN project aimed at building a muon collider, and participated in two test beams which took place at CERN in August and September 2018, and now I am involved in the analysis of data collected in these test beams. I am also currently working on the CMS muon trigger upgrade for LHC Phase II.
