I am a Fellow of the Alexander von Humboldt Foundation, hosted by the University of Göttingen. My research focuses 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 research focuses on 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 lead their interpretation in the framework of Effective Field Theory. With colleagues from the CMS collaboration, I am preparing the very first cross-experiment combination of top+X results. I also plan to be involved in the further development of the MadGraph Monte Carlo event generator.
Other responsibilities include:
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.
