Andrej is a senior researcher at the Jozef Stefan Institute, Ljubljana, Slovenia, working at the Experimental Particle Physics Department. So far he worked for experiments at three different laboratories: DESY in Germany, KEK in Japan, and CERN crossing the Franco-Swiss border. Currently he is part of the ATLAS experiment at the Large Hadron Collider (LHC), CERN, where he engages in exotic searches and in development of new solid state detectors for high radiation environments at high energy physics experiments. Some of them will possibly be used for the next generation of particle tracking detectors while few of them are already installed in the ATLAS experiment measuring luminosity, beam conditions and protecting ATLAS Inner Detector from anomalous beam behaviour. Many of them are made of extremely pure version of pCVD diamond material.
Andrej decided to become a physicist already very early on at the end of primary school, partially due to exposure to an excellent TV series Cosmos by Carl Sagan. He thinks that outreach is very important especially for attracting young people and wakening their interest in physics and in science in general. Since 2016 he is organising the International Masterclasses in Slovenia and is Slovenia's first representative to IPPOG since it joined in Spring 2016.
