Earlier this month, NIH announced the Grant Support Index (GSI), a new policy that will limit the number of grants that any single principal investigator (PI) can have at one time. Limiting the number of grants per PI should allow more funds and grants to be available to support a broader and more diverse array of investigators and stabilize funding of PIs.
While implementation of a GSI limit is estimated to affect only about 6 percent of NIH-funded investigators, it is expected that, depending on the details of the implementation, it would free up about 1,600 new awards to broaden the pool of investigators conducting NIH research and improve the stability of the enterprise.
NIH is still finalizing several details surrounding GSI. More information will be forthcoming.
