Stefan has been with the CMS experiment at CERN since its very beginnings back in 1992. Having helped design, prototype and build the Hadron Calorimeter, Silicon Tracker, and Resistive Plate Chamber sub-detectors of the experiment, and the Monte-Carlo simulation framework of the project, he recently concentrated his efforts on the Computing Model and Infrastructure of the experiment.

After spending many years at CERN and FermiLab as a Guest Scientist, and Assistant Professor at Brown University, in 2017 Stefan joined the Research Computing team at Purdue to run one of the most successful Tier-2 centers of the CMS Collaboration worldwide.

CMS and ATLAS collaborations jointly discovered the Higgs Boson in 2012, for which the Nobel Prize in Physics was awarded in 2013.
