(Reissue of PAR-18-486, PAR-21-153) The purpose of the NINDS Faculty Development Award to Promote Diversity in Neuroscience Research (K01) is to diversify the pool of independent neuroscience research investigators by providing junior faculty with research cost support, protected research time and career stage appropriate professional development mentorship in neuroscience research. Individuals from backgrounds underrepresented in biomedical research are eligible for support under this award if they have doctoral research degrees (Ph.D. or equivalent) and are in the first 3 years of a faculty tenure track or equivalent position at the time of application.This Funding Opportunity Announcement (FOA) is designed specifically for applicants proposing to serve as the lead investigator of an independent clinical trial, a clinical trial feasibility study, or a separate ancillary study to an existing trial, as part of their research and career development. NINDS will only accept applications to this FOA that propose human mechanistic trials/studies that meet NIH's definition of a clinical trial and that fall within the NINDS research priorities. Applicants are strongly advised to consult with NINDS program staff prior to submitting an application with human subjects to determine the appropriate funding opportunity.
