Activities

I have been involved in many activies in the ATLAS collaboration. See my CV for details.

Performances

energy calibration, reconstruction, e/gamma coordinator

Since the beginning of my PhD, I have maintained and improved the Monte Carlo energy calibration of electrons and photons using machine learning.

I coordinated the e/gamma group in 2022-23 and several subgroups (calibration 2014-16 and reconstruction 2020-21).

Physics

inclusive photon, diphoton, H→γγ, photon-jet searches, γγ exotic searches

During my PhD I have worked in the inclusive photon and diphoton analysis. Then I focused on the H→γγ. At the beginning of Run2 I have moved to the photon-jet analysis and to the search of New Physics in the γγ channel. In 2016-2017 I have been analysis contact for the Higgs coupling measurement in the diphoton channel and the Higgs mass measurement.

In 2017-19 I have coordinated the HGam subgroup

Detector

Lar High Voltage

I was a hardware on-call expert and a developer of the Detector Control System for the ATLAS Liquid Argon system

Software

everytime!

I have particular interest in software. I have developed a web monitor for the space token usage in my institute. I have tested proof performance on a local cluster. I am a little constributor of the rootpy project. I am the maintainer of several tools used by the collaboration. I developed a tool to easily manage a full list of publication from Inspire HEP and a tool to semi-automatize the loading of publication informations on AIR.

Teaching

I have been assistant of prof. Fernando Palombo during the course "Laboratory of Numerical Treatment of Experimental Data" and of prof. Leonardo Carminati during the course "Laboratory of Numerical Treatment of Experimental Data" and of prof. Attilio Andreazza during the course "Istituzioni di Fisica Nucleare e Subnucleare". I have made a series of lectures about statistics for PhD students.
I’ve been the supervisor of a CERN summer student working in the MVA energy calibration. I have been the supervisor of many students.
