The Research Development Core provides support for researchers nation- and world-wide, most often junior faculty, to develop pilot data to aid in new project and career development. This is assisted by granting of competitive awards for pilot project support for studies in the basic biology of aging, using the key resources provided by our Resource Cores. Successful pilot projects will capitalize on the strengths of our four Resource Cores and awardees will be mentored by a senior investigator in the biology of aging. The Pilot Project program will be actively advertised and applications solicited nation-wide. The great majority of awards have been, and will continue to be made to investigators outside our region.
