Scientific Fellowships and Trainees

The Intramural Research Program (IRP) is the internal research program of the National Institutes of Health (NIH), known for its synergistic approach to biomedical science.

With 1,200 Principal Investigators and over 4,000 Postdoctoral Fellows in basic, translational, and clinical research, the IRP is the largest biomedical research institution on earth.

The unique funding environment of the IRP facilitates opportunities to conduct both long-term and high-impact science that would otherwise be difficult to undertake. With rigorous external reviews ensuring that only the most outstanding research secures funding, the IRP is responsible for many scientific accomplishments, including the discovery of fluoride to prevent tooth decay, the use of lithium to manage bipolar disorder, and the creation of vaccines against hepatitis, Haemophilus influenzae (HIB), and human papillomavirus (HPV).
