Lecturer's references
Doc. dr. Gabrijela Zaharijas is an assistant professor at the University of Nova Gorica. Dr. Gabrijela Zaharijas je docentka za področje fizike na Univerzi v Novi Gorici.
She works within two big experimental collaborations: the Fermi LAT (a NASA/European gamma ray satellite in its seventh year of mission) and the CTA (which is a worldwide experimental collaboration set to build a full kilometer square array of ground based gamma ray telescopes). Dr. Zaharijas developed her career at several institutes, both in the US (New York University and Argonne National Lab, Chicago) and Europe (Stockholm University, Centre for Atomic Energy in Paris and International Centre of Physics in Trieste) before joining the astroparticle group of the University of Nova Gorica.
