IMAT Publication Trends


The IMAT Program has supported nearly 500 investigator-initiated research project grants through 6 funding mechanisms (R21, R33, R41, R42, R43, and R44) from the program’s inception in 1998 through 2007. The program continues to fund new research awards and currently has 5 strategically-driven funding opportunity announcements soliciting applications for cutting-edge, transformative technologies.  The following data is representative of the program’s growth and output as a function of direct project-related publications.

Significant Results

  1. The number of publications citing IMAT grants markedly increased in the first 4 years of funding, after which the numbers remained steady. This result is consistent with a set of new awards that require a few years of research to be able to consistently publish results. Approximately 140 project-related publications were published in calendar year 2007, indicating a respectable level of productivity and dissemination. 


  1. The data expressed above includes only publications in PubMed that cite a specific IMAT grant number, which assumes that all PIs are acknowledging this information in the article/publication. The number of project-related publications that result without citation of a specific IMAT grant number can therefore be much larger.
  2. The data collection also assumes that all journals are publishing the grant numbers and providing them to PubMed. However, it is known that a small number of journals do not report grant numbers to PubMed.
  3. These results do not differentiate the type of journal article—all types are included. For example, a review, a journal article, and a letter all could be represented in these results.
