High energy particle physics has been an important repeating theme in Krzysztof’s scientific path. Krzysztof’s PhD thesis was based on the data collected from measurements in the nuclear emulsion - a technique known already since before 1940, but which nowadays is still used in neutrino experiments. Later he started to work in experiments with detectors full of electronic devices that would process data with computers. Here he was able to fully apply his skills gained during computer science studies, and his interest in HEP experiments continued to grow.
For a long time Krzysztof worked for the PHOBOS experiment at Brookhaven National Laboratory measuring collisions of gold nuclei at RHIC. Such collisions of nuclei provide nuclear matter with extremely high energy density suitable for creation of a new state of matter - Quark-Gluon Plasma. More recently, unlike the alchemists, he switched his interest from gold to lead and got involved in the ATLAS experiment at CERN where the Large Hadron Collider delivers even heavier nuclei at much higher energy.
Krzysztof considers outreach an important activity for scientists, especially as the Large Hadron Collider gains a lot of public attention. After an involvement in the LHC exhibition in Poland he joined IPPOG in 2011 and organizes IPPOG Masteclasses in Krakow. "We owe society information on recent developments in science. They demonstrate the beauty of the universe, complicated but purposeful laws discovered by us and mysteries of it's creation..."
