I am a specialist in experimental nuclear physics and elementary particles. I took part in numerous elementary and heavy-ion collision experiments. I hold experience in the data analysis and Monte Carlo simulations of elementary collisions, in particular the identification of rare dielectron probes. I am the co-author of the partial wave analysis (HADES experiment), which results are published also in The Review of Particle Physics (Particle Data Group) - branching coefficients: decay Delta Dalitz and N (1520) and N (1535). My habilitation monograph is a source of information on the production and decays of baryon resonances in nucleon-nucleon collisions at energies up to a few GeV.

I am experienced in modern programming in C ++, including multithreaded programming. In addition, I am a long-term lecturer of object-oriented and generic programming. I teach Python language, too.

I am a member of the ATLAS (CERN) research group led by prof. E. Richter-Wąs. Together with the group from AGH in Krakow, we develop the High-Level Trigger system. I plan to participate in the upcoming Run3 measurement period and analyze pp elementary collisions, including the reconstruction of the Higgs boson. The measurement perspective of the ATLAS experiment also poses challenges related to a large increase in beam intensity in Run4 and thus data recording conditions based on algorithms implemented e.g., on GPUs, and ML techniques.
