Co-PI stands for Co-principal investigator, an academic abbreviation.

Researcher who shares leadership of a grant-funded project with the principal investigator, often contributing specialized expertise and supervising part of the work. The title is used formally by the National Science Foundation and informally elsewhere.

Example: Dr. Kim joined the proposal as co-PI to lead the statistical modeling.

Usage notes

NIH applications instead designate multiple PIs, one of whom serves as contact PI. Co-PI status helps junior faculty demonstrate grant leadership for tenure. Because definitions differ by agency, institutions often have policies on who is eligible to serve as PI or co-PI.
