ITHS requires the applicant to designate one of the PIs as the Contact PI. This person is responsible for communication between the PIs and ITHS but has no special authorities or responsibilities within the project team. In many ways, a Contact PI is analogous to a corresponding author on a publication. The Contact PI must serve as a member of the PI team and must meet all eligibility requirements for PI status. In those projects where there is an identified project coordinator, the coordinator could serve as Contact PI or that role could be assigned to another PI. It will be possible, and may even be desirable, for the grantee institution to periodically designate a change in Contact PI. For example, it may be desirable to rotate the role of Contact PI among the multiple PIs on an annual basis at the time of grant renewal. Note that the Contact PI must be associated with the applicant/awardee institution.
