Aleksandar Belic gave an invited talk at the FIS'07 HEP conference (Fundamental Interactions Serbia) held in Fruska Gora, Serbia. The talk "Pan-European Grid e-Infrastructure for LHC experiments at CERN - SCL's activities in EGEE" focused on the use of Grid computing as a crucial tool in modern High Energy Physics. In particular, the talk was a chance to inform Serbia's HEP community about SCL's participation in EGEE and SEE-GRID projects and about Serbia's Grid infrastructure available to the researchers through AEGIS (Academic and Grid Initiative of Serbia).
