IIT scientific activity is based on a 6-year strategic plan. The strategic plan is proposed by the Scientific Director and a panel of IIT senior scientists and is approved by the Scientific Technical Committee (STC), the Executive Committee and the Board of the Foundation. The Strategic Plan is periodically updated under the supervision of the STC. The Strategic Plan (2018-2023) consists of 4 Research Domains. Each Domain is developed by a number of fully independent Principal Investigators (PIs). PIs and their teams develop their Research Line and contribute to one or more Domains, according to a Research Matrix of the Institute.
