Department Head (IT Department)



Overall management of the IT Department. Its mission is to provide the information technology required for the fulfilment of the laboratory’s mission in an efficient and effective manner, including storage, network and support for the LHC and the rest of the experimental programme, as well as services for the accelerator complex, the whole laboratory and its users.  It also provides a ground for the development of new technologies and advanced R&D with various partners. IT notably leads the Worldwide LHC Computing Grid collaboration, the CERN openlab, the Helix Nebula initiative, hosts the UNOSAT organization and participates in about 6 H2020 projects co-funded by the European Commission. IT Department has a budget of ~80 MCHF in 2015, including ~210 staff positions.
