Multiple principal investigators« Back to Glossary Index
Multiple principal investigators (multiple PIs) is the term preferred by the National Institutes of Health (NIH) in the grant process when more than one of the investigators share equally the authority and responsibility for leading and directing the project, intellectually and logistically. Each PI is responsible and accountable to the applicant organization, or as appropriate to a collaborating organization, for the proper conduct of the project or program, including the submission of all required reports. The presence of more than one PI on an application or award diminishes neither the responsibility nor the accountability of any individual PI.
