Principal Investigator
Co-Principal Investigator (Co-PI) role being phased out (July 2026)
As of July 2026, the Co-PI role is being phased out. Individuals who were listed as Co-PIs in iRIS can retain this role, but no new Co-PIs can be added int he Research Gateway IRB (ReGI) system. Please add these individual as Co-Investigators instead.
Individuals with the legacy Co-PI role must be eligible to be a UCSF PI (see PI eligibility above) and continue to be prepared to assume the responsibilities of the PI when the PI is unavailable.
PI Proxy Role
ReGI has a new role called PI Proxy. This is a system role, not a study role, that is assigned by the PI. Assigning someone as a PI Proxy authorizes them to submit items in ReGI on behalf of the PI, but it does not confer any of the PI’s responsibilities for the conduct of the study. Review the PI Proxy Guidance and Assign PI Proxies user guide for more information and step-by-step instructions on how to assign this role.
Clinical Research Coordinators (CRCs)
The CRC works with and under the direction of the PI. Although the PI is legally responsible for all aspects of the research study, the CRC often handles the bulk of the daily study activities and plays a key role in the study conduct and management. Learn more about the responsibilities of a CRC here.
