My Career

I’m a particle physicist with a strong passion for uncovering the fundamental building blocks of our universe. Here’s a brief overview of my academic and research journey so far.

Post-doc

I joined the University of Manchester in November 2019 as a Research Associate.
My work focuses on precision measurements of the Higgs boson properties, using the ATLAS detector at CERN.

I designed and led the very first ATLAS measurement of the associated production of the Higgs boson with a single top quark (to be published soon…).

A significant part of my research is dedicated to the identification of heavy-flavoured jets and the evaluation of their performance in collision data.
I am currently the convener of a fantastic team that developed a transformer-based algorithm, which has significantly improved heavy-flavour identification performance within the ATLAS detector.

Here is one of the plots I’m most proud of — it highlights the historical improvement in performance and how well it holds up with actual collision data:

Ph.D

My Ph.D. thesis introduced a novel method to extract the top-quark coupling to the bottom-quark. It also included the measurement of heavy-flavour tagging performance using multi-jet events, and the construction of Micromegas detectors for the upgrade of the ATLAS Small Wheel 1 2.

During my Ph.D I was awarded a prestigous fellowship by INFN (Istituto Nazionale Fisica Nucleare) that allowed me to spend one year at CERN.

Master’s

For my Master’s thesis, I contributed to the first evidence of the associated production of the Higgs boson with a pair of top quarks, achieved in 2018.

In 2015, I spent a summer in Chicago working as an intern at Fermilab National Lab.
There, I developed a new method for optimizing electron selection for the W-asymmetry measurement, using the CDF detector.
