As of September 1, 2009, the NHLBI has supported hundreds of principal investigators (PIs) with American Recovery and Reinvestment (the Recovery Act) funds, using existing mechanisms, such as expansion of the research paylines from 2008 and 2009, as well as new programs created specifically for the Recovery Act, including Challenge Grants, and Grand Opportunities (GO) grants. Learn more about the scientists who are directing projects or programs supported by grants.

Principal Investigators

Principal investigators, often referred to as PIs for short, are the lead scientists in charge of a research project or program; they are responsible for overseeing the scientific and technical aspects of the research, including its day-to-day management. Through the American Recovery and Reinvestment Act (the Recovery Act), the NHLBI is funding an increased number of investigator-initiated research grants on the cause, prevention, diagnosis, and treatment of heart, lung, blood vessel, and blood diseases and sleep disorders. The Recovery Act allowed the NHLBI to boost funding for scientists whose grant applications were rigorously peer-reviewed by expert panels and found capable of making advances in their research with a two-year grant.

Early Career Researchers

Researchers in the early stages of their careers represent the future of biomedical research. Most of them have only recently completed their research degree or medical residency and have not previously served as a principal investigator on a major NIH-funded research project. Fostering the careers of America’s future biomedical leaders is a key objective for the NHLBI. The Recovery Act has enabled the creation of funding awards designed to establish more opportunities for biomedical scientists and to create hundreds of jobs in research institutions across the country.

Summer Interns and Science Educators

High school students, college students, and science educators from elementary, middle school, high school, community college, and non-research intensive institutions benefit greatly from summer research experiences. In keeping with the spirit of the Recovery Act, the NHLBI supported opportunities for such individuals to spend time in a laboratory on the NIH campus or in a laboratory of a funded scientist across the country. In 2009, more than 200 researchers from around the country have received funding through the Recovery Act to mentor students and educators.
