Overall Recruitment

Recruitment of the ESRs by all beneficiaries

Supervisory Board of the network

The Supervisory Board as the executive body of the ETN; The Supervisory Board (SB) will be responsible for the overall strategic and scientific management of the network and reports directly to the GA. The SB will be composed of the coordinator, the supervisors, the co-supervisors and external stakeholders from industry and government. The diversity of this board is intended to ensure ongoing relevance of the Network and that integration benefits from the expertise of all relevant parties. The supervisory board will meet once per year and will be in contact by electronic means for intermediate status reports and discussions. The annual meetings of supervisory board, general assembly meeting and fellow council meeting will be co-located with network wide training events in order to keep travel overhead low. External stakeholders that will serve on the Supervisory Board include Claire Vishik (Intel), Moti Yung (Google), and Kaisa Nyberg (Aalto University); in addition a representative from ENISA (European Network and Information Security Agency) will be invited. The Supervisory Board oversees integration of the research goals within the project and provides advice on all strategic issues relevant to both scientific and administrative aspects. The Supervisory Board will fulfil other specific tasks including the initiation, coordination and organization of the workpackages and the support of the Coordinator in its tasks. It will also monitor and coordinate all planned trainings events within the ITN. The Supervisory Board will be responsible for adjusting the work plan if there are any disruptions such as the recruitment not going to according to a plan, or fellow leaving the network and so on. The supervisory board will meet once per year and will be in contact by electronic means for intermediate status reports and discussions.
