Mateusz Zarucki

CERN Senior Fellow (for Task 3.4)

Driven by the pursuit of answers to the most fundamental questions about the universe, my work spans physics analysis, software development, and detector operations, with a growing focus on high-performance computing and novel technologies for detector upgrades.

Born in Warsaw and raised in Vienna, I completed my Master’s in physics at Imperial College London, including an Erasmus year at the University of Valencia, working with the NEXT experiment on the search for neutrinoless double-beta decay. I then completed my doctorate at HEPHY and TU Wien, with a thesis on background modelling and trigger algorithms for SUSY searches with CMS. As a PostDoc at the University of Notre Dame, I led a team responsible for the HLT operations of CMS, overseeing the successful startup of LHC Run 3, including the commissioning of GPU-based heterogeneous reconstruction. Currently, as a CERN Fellow, I work on the Phase-2 upgrade of the HLT for the HL-LHC as part of the NGT project. My focus is on developing a system that derives optimal detector calibrations in real time during data-taking, taking advantage of data buffering online.

I believe overcoming real-time data processing limitations holds the key to expanding our reach for physics beyond the Standard Model. My research interests lie at the intersection of data science and analysis, trigger and DAQ systems, and reconstruction algorithms, with a particular enthusiasm for machine learning, artificial intelligence and high-performance computing to tackle the challenges of future next-generation experiments
