Approximately 1,200 Principal Investigators (PIs) conduct biomedical or behavioral research within the Intramural Research Program (IRP). Although each Investigator is organizationally aligned with a particular Institute or Center, collaborations are not limited to the NIH campus, and many of our PIs work extensively with scientific colleagues both nationally and internationally. Working in scientific laboratories, hospital clinics, and fieldwork stations around the world, our Investigators are constantly advancing the state of biomedical science with the goal of changing lives for the better.

We are currently adding pages to include all PIs within the IRP. Please visit us again soon to see our progress.
