NIGMS continues to support a broad range of scientific topics and investigators within its research portfolio, including support for investigator-initiated research project grants (RPGs) at institutions throughout the country. As part of its commitment to transparency, NIGMS examines and publishes data on annual trends reflected in its RPG portfolio. In this post, we review and describe investigator-level trends associated with competing R01/R01-equivalent RPGs including those in the Institute’s R35 Maximizing Investigators’ Research Award (MIRA) program.
