The purpose of the NINDS Alzheimers Disease and Alzheimers Disease-Related Dementias (AD/ADRD) Advanced Postdoctoral Career Transition Award to Promote Diversity (K99/R00) program is to support of a cohort of new and talented, independent investigators from diverse backgrounds conducting AD/ADRD research. The program is designed to facilitate a timely transition of promising postdoctoral researchers from diverse backgrounds (e.g., see NIHs Interest in Diversity) from their mentored, postdoctoral research positions to independent, tenure-track or equivalent faculty positions. The program will provide independent NIH research support during this transition in order to help awardees establish independent research programs in the AD/ADRD field. This FOA is designed specifically for applicants proposing research that does not involve leading an independent clinical trial, a clinical trial feasibility study, or an ancillary study to a clinical trial. Applicants to this FOA are permitted to propose research experience in a clinical trial led by a mentor or co-mentor.
