I am a Fellow of CERN, the European Organisation for Nuclear Research. I focus on searching for new physics at the Large Hadron Collider with the ATLAS experiment, using precision measurements of the top quark and machine learning tools.

My CERN fellowship is split between my work on the ATLAS experiment at the LHC and preparations for the future ALLEGRO detector at the FCC. My research focuses on connecting quantum information theory with particle physics, particularly in the top quark and Higgs boson sectors. I am also involved in performance studies of tile calorimeters for FCC.
Other responsibilities include:
During my Humboldt fellowship, I studied the electroweak couplings of the top quark: $t\bar{t}Z$, $tZq$, $tWZ$ and $t\bar{t}\gamma$. Besides my contributions to the measurement of these Standard Model processes with the ATLAS experiment, I led their interpretation in the framework of Effective Field Theory. With colleagues from the CMS collaboration, I prepared the very first cross-experiment combination of top+X results. Last but not least, I helped set up the first efforts on quantum entanglement and the violation of Bell’s inequalities in top quarks and Higgs bosons.
Other responsibilities included:
I led the legacy $t\bar{t}Z$ ATLAS measurement and contributed to the first measurement of the $t\bar{t}$ spin density matrix with the full Run 2 dataset; for both analyses, I developed an extensive Effective Field Theory fitting framework in the Julia language. I was also involved in background estimations for a combination of Dark Matter searches with $t\bar{t}+E_\mathrm{T}^\mathrm{miss}$ signatures, as well as prototyping an auto-encoder for an Anomaly Detection based search for new physics.
Other responsibilities included:
Spin correlations between the top quarks in the $t\bar{t}Z$ process are sensitive to new physics. In this phenomenological paper, I predict their values according to the Standard Model, go beyond it with Effective Field Theory, and show that, while a very challenging experimental measurement, there is a case for performing this analysis already with the LHC Run 2 dataset.
