CERN — the European Organization for Nuclear Research

Bulgarian Academy of Sciences Institute for Nuclear Research and Nuclear Energy (INRNE) 72 Tzarigradsko chaussee, Blvd. 1784 Sofia, Bulgaria

Stefan’s firm interest in science began at a very young age and grew steadily through the years.  Fuelled by this interest, he attended the national high school for math and sciences where he studied physics. Later, at Sofia University, he was inspired by experimental high-energy physics and chose to write his master's degree thesis on the Hadron Calorimeter of the CMS detector on the LHC. It was this thesis project that first brought Stefan to CERN in 1994.   Ever since, Stefan has returned frequently to CERN to spend periods of time working on various parts of CMS such as the Hadron Calorimeter, the Silicon Tracker, and computing.  Stefan was involved with the computing project of the HARP Experiment in 2000-2001.  Between 2003 and 2008 he spent five years at Fermilab in the USA working on the HCAL test beam program of CMS.  Stefan was appointed as the Bulgarian IPPOG member representative when Bulgaria joined CERN in 1999.  Currently he is involved in CMS computing.  “By reaching out to the public, Particle Physics tries to ignite the spark of inquiry in every mind.”
