Between 2014 and 2018 I’ve been doing my PhD studies at the Technical University of Munich, Germany, which were dedicated to the analysis of low-mass dielectron production in pp collisions at a center-of-mass energy of 13 TeV. After completing the PhD studies I stayed at the TUM but changed the research topic to antinuclei in space, which are believed to be a great probe for indirect dark-matter searches. Thinking outside of the box, we turned the ALICE detector into a fixed-target experiment to quantify inelastic interactions of rare antinuclei, using collisions of protons and heavy ions at the LHC as an antimatter source and the ALICE detector material as a (active) target. At the same time I stayed connected to the dielectron analyses, serving as coordinator of the Physics Analysis Group “Low-Mass Dielectrons” (PAG-LMee, between 2021 and 2023) and the Physics Working Group “Electromagnetic probes” (PWG-EM, since March 2024).

In September 2022 I joined CERN team as a research fellow, studying direct-photon production in small systems with full Run2 data sample as well as looking for antihelium-4 signal in Run3 pp collisions. From this moment I also started to be actively involved in the NA60+ project at CERN, which is proposed to examine in detail (among other objectives) thermal radiation and chiral symmetry restoration at the SPS energies.

In my free time I like to enjoy the mountains around Geneva, including but not limited to hiking activities in summer and alpine skiing in winter, alongside with running and playing football all year long.
