Short presentation

I am a member of the ATLAS Collaboration, the largest experiment at the Large Hadron Collider (LHC) at CERN. From 2006 until 2018, I was a member of the CMS Collaboration.

Research

I am a physicist on the ATLAS collaboration at the LHC and previously worked on the CMS collaboration, with more than a decade of public-engagement experience. I have been involved in Higgs boson physics since the start of my PhD, covering the search for the Higgs boson in WW decays; all the way until the observation of ttH in 2018, being the Higgs to WW subgroup convener in CMS (2015-2016).

In 2011 I started studying the top quark, becoming the single top subgroup convener (2013-2014) after achieving the first observation of single top tW. I coordinated the whole Top Quark Physics Analysis Group in CMS from 2016 until 2018, when I left CMS to join the Uppsala ATLAS group after obtaining an individual starting grant from the Swedish Research Council (VR 2017-05092). While in CMS, I worked extensively in detector operation, in the DT Muon chambers, and the Silicon Strip Tracker.

From 2021 until 2023 I was the Outreach & Education coordinator in ATLAS. Before that I was involved in the Hardware Track Trigger (HTT) project for the Phase-II Upgrade.

Searching for a dark sector in ATLAS (latest paper: JHEP 09 (2024) 005), developing machine learning techniques for high energy physics (SciPost Phys. 18 (2025) 080), and exploring opportunities for new physics searches at future colliders (Phys.Rev.D 111 (2025) 3, 035029, arXiv:2412.10141) are my top priorities. Concerning the later I convene both the “Direct discovery potential” working group (WG1-SRCH) of the ECFA Higgs Factory Study and the BSM Physics Performance group for the Future Circular Collider (FCC). In 2024 I was selected to be the BSM physics working group convener for the next Update of the European Particle Physics Strategy.

The ongoing lines of research of my group are:

New Physics searches at the LHC, HL-LHC, and Future e+e- colliders, in particular FCC
Unconventional experimental signatures from hidden sectors connected to main physics questions (e.g. dark matter, neutrino masses): long-lived particles, dark showers
ATLAS service work in: Luminosity, Outreach, Software & Computing
E-Science (ML/AI) methods for big data processing and analysis, related to the previous points
