Principal Investigators

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.

Below are profiles of Recovery Act-funded scientists who provided their photographs to the NHLBI. To find out more about their projects or to see all the NHLBI-funded Recovery Act projects, use the search tool on the right. If you are a PI, please consider sharing your Recovery Act story and photograph for publication on these Web pages.
