Research Activity
My research activity is in the context of the CMS collaboration at the Large Hadron Collider, CERN, Geneva. My main contributions to the research activities of the collaboration consist in technical activities, data analysis and coordination roles and responsibilities.

Research activity - technical
2015-2016 - I edited the section about the DT (Drift Tubes) detector, the muon detector covering the central part (barrel) of CMS, in the CMS Technical Proposal for Phase2 Upgrade (CERN-LHCC-2015-010). The muon identification performance
has been studied simulating the detector and electronics aging, and a proposal for the construction of new processors has been outlined. Such devices will be capable of producing Level-1 trigger track candidates with a resolution similar to what is today available offline. I have then studied the aging of a DT chamber using the GIF++ irradiation facility at CERN, analyzing the data that were collected with a muon beam (hit efficiency, segment reconstruction, trigger performance - as a function of the adsorbed dose).
2012-2013 - I contributed to development, design and test of a new optical link system for the DT detector, within the context of the "Phase-1" upgrade of CMS. Installed and commissioned during the Long Shutdown 1 (2013-2014), it is now taking data during the LHC Run2, and delivers the informations for the tracking of muons in the barrel region to the new Level-1 trigger system.
2007-2009 - I integrated digital electronics modules and developed the online control software for the DT trigger system. I studied the performance of the system and I defined the algorithms to ensure the synchronization of the electronics to LHC beams [7,10,11]
2001-2006 - In between my participation to the Summer Student program at CERN and the end of my PhD activities, I contributed to the design and construction of the Level-1 trigger for the barrel region of CMS. I developed a VHDL implementation of the algorithm for the tracking of muons in the longitudinal view. Afterwards, during my work for the diploma thesis, I started the design of the muon selection system [12], using programmable processors (FPGA). I completed the construction of such system during the PhD, and I implemented the system connecting the counting room to the on-detector electronics, using radiation-tolerant technologies and methods and high-speed optical links. I used prototypes of the modules I designed at a test beam (H2 SPS/NA at CERN) [13,14,15] and I implemented a full test system for the mass production (~400 digital modules). I also regularly contributed to the construction of DT chambers, at INFN-LNL, and to the assembly and test of minicrate systems, in Bologna INFN laboratory.

Research Activity - simulation and analysis
2017 - editor of trigger, reconstruction e physics performance chapters in the Technical Design Report about the "Phase-2" upgrades of the CMS muon systems (in preaparation).
2013-2015 - I studied the Standard Model Higgs Boson in four-lepton decays [1,4,5]. I studied the selection of the signal, including the lepton identification algorithms, isolation and fake rates, for different instantaneous luminosity scenarios and CMS configurations, the goal being the definition of upgrade strategies for the "Phase-1" upgrade of the Level-1 trigger (TDR in 2013, CERN-LHCC-2013-011) and for the "Phase-2" upgrades at High-Luminosity LHC, expected for around 2024 (Technical Proposal in 2015, CERN-LHCC-2015-010 and the following Scope Document, CERN-LHCC-2015-019).
2014-2016 - I developed in the context of the "Phase-1" upgrade of the Level-1 trigger new muon tracking algorithms, exploting the combination of DT and RPC detectors, including a more powerful algorithm for measuring the transverse momentum. Then I improved the simulation to understand the effect of different options of the complexity of the algorithm (and thus hardware resources), and also to verify the robustness and redundancy by applying malfunctioning scenarios.
2013 - I joined a task force devoted to the measurement of the branching ration of the Bs decay in two muons [2,3], published in 2013, defining the strategy to include trigger effects in the measurement of the lepton fake rates.
2012 - I worked at DT detector performance analyses [6] during data taking at LHC, improving Data Quality Monitoring tools and the Data Certification process, and offline release validation.
2009-2011 - I coordinated the analysis of the performance of the Level-1 trigger of CMS [8,9], during the cosmics commissioning and during the data taking at LHC Run 1. I worked at trigger objects validation criteria, at the development of the Data Quality Monitoring system, at Data Certification, at the definition of the trigger algorithms used during the data taking (Trigger Menu).

Research Activity - responsibilities and coordination roles
