Glenn Foundation for Medical Research Breakthroughs in Gerontology Award - LOI due Dec. 16, 2019
https://www.afar.org/research/funding/big/
To be eligible, applicants must at the time they submit their proposal be full-time faculty members at the rank of Assistant Professor or higher. To be competitive at the Assistant Professor level, a candidate would be expected to have established R01 or equivalent funding. 
The "Breakthroughs in Gerontology (BIG)" initiative provides timely support to a small number of research projects that are relatively high risk but which offer significant promise of yielding transforming discoveries in the fundamental biology of aging. Projects which build on early discoveries that show translational potential for clinically-relevant strategies, treatments and therapeutics, addressing human aging and health span are also considered.

Glenn Foundation for Medical Research and AFAR Grants for Junior Faculty - LOI due Dec. 16, 2019
https://www.afar.org/research/funding/afar-research-grants/
The major goal of this program is to assist in the development of the careers of junior investigators committed to pursuing careers in the field of aging research. GMRF and AFAR support research projects concerned with understanding the basic mechanisms of aging rather than disease-specific research. Projects investigating age-related diseases are supported if approached from the point of view of how basic aging processes may lead to these outcomes. Projects concerning mechanisms underlying common geriatric functional disorders are also encouraged, as long as these include connections to fundamental problems in the biology of aging. Projects that deal strictly with clinical problems such as the diagnosis and treatment of disease, health outcomes, or the social context of aging are not eligible.
