The Principal Investigator (PI) Committee of the ECOG-ACRIN Cancer Research Group is one of two committees that govern the Group under the leadership of the Group Co-Chairs (the other is the Executive Committee). The PI Committee sets Group policy, approves new members, approves principal investigators at member institutions, participates in annual reviews of member institutions, and approves changes to the ECOG-ACRIN constitution when necessary. It also elects Group Co-Chairs, as needed, through its Nominating Committee.

Voting Privileges

The constitution document defines which member institutions are eligible for voting privileges (Article IV). In addition, members with voting privileges must remain in good standing through ECOG-ACRIN’s annual merit-based institutional evaluation process. Each voting member institution has a single vote on the committee, cast by its designated principal investigator (PI). The entire Affiliate Member classification has a single vote, cast by an investigator chosen by the Affiliate Members. Once voted in, individuals may serve as long as the member institution designates them to do so, and provided that the institution remains in good standing.
