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