Early Stage Investigator ESI
An Early Stage Investigator is a Program Director / Principal Investigator (PD/PI) who has completed their terminal research degree or end of post-graduate clinical training, whichever date is later, within the past 10 years and who has not previously competed successfully as PD/PI for a substantial NIH independent research award. See our list of NIH grants that a PD/PI can hold and still be considered an ESI. For more information, please click here.
