Integrated Review Groups

Review activities of the Center for Scientific Review (CSR) are organized into Integrated Review Groups (IRGs). Each IRG represents a cluster of study sections in a general scientific area. Applications generally are assigned first to an IRG, and then to a specific study section within that IRG for evaluation of scientific merit.
A list of the IRGs is below. For each of the IRG's study sections, a general description, specific research areas covered, and shared interests with other study sections are given.
Click on an individual IRG below to view a listing of all study sections and abbreviations, names of the Scientific Review Officers (SROs). Meeting rosters can be found at
The study sections within the various IRGs mainly review research project grant applications and a few Research Career Award applications. Most National Research Service Award individual fellowship applications (NRSA) are reviewed in special study sections that are designated for these reviews.
