OPA is an interdisciplinary team that impacts NIH-supported research by enabling NIH decision makers and research administrators to evaluate and prioritize current and emerging areas of research that will advance NIH’s mission.

What We Do

Our iSearch COVID‑19 portfolio, which includes peer-reviewed articles from PubMed and preprints from medRxiv, SSRN, arXiv, bioRxiv, Research Square, and ChemRxiv, is updated daily with the latest available data.
