There is no "interdisciplinary panel" for the evaluation of interdisciplinary proposals. The Principal Investigator has to indicate a primary evaluation panel, i.e. the respective ERC evaluation panel which he/she thinks is most suited to assess the topic of the research project. If the proposal is considered to be interdisciplinary, the PI may select another evaluation panel (secondary evaluation panel). Furthermore, the Principal Investigator can chose one or more keywords (selected from a drop-down list) to describe the area of the project in more detail. The assignment of the proposal to peer reviewers will be made by the Panel Chairs on the basis of the information given. The primary panel will then decide whether the proposal is interdisciplinary (cross-panel or even cross-domain) and if its evaluation requires additional expertise from other panels.
