This announcement provides support to eligible, domestic institutions to develop and implement effective, approaches to biomedical research education and mentoring that will keep pace with the rapid evolution of the research enterprise. This NIH Neuroscience Doctoral Readiness Program (DR Program) expects that the proposed research education programs will incorporate extensive research experiences within the NINDS mission and well-designed courses for skills development and education to prepare recent baccalaureates from diverse backgrounds to transition into and complete rigorous, research-focused doctoral degree programs (e.g., Ph.D. or M.D./Ph.D.) in biomedical fields.This is a limited competition funding opportunity announcement to support postbaccalaureate programs that will be affiliated with a funded NIH T32 program. Eligibility is limited to PD(s)/PI(s) or MPI teams that include at least one PD/PI of a grant supported by the following FOAs: T32 - Jointly Sponsored Institutional Predoctoral Training Program (JSPTPN), PAR-20-076;NINDS T32 - Institutional Research Training Grant, PAR-21-149; or NINDS T32 - Institutional Translational Research Training Program, PAR-19-228. In all cases, a PD/PI of the T32 grant from a FOA cited above, must be the PD/PI or an MPI of this R25.This Funding Opportunity Announcement (FOA) does not allow appointed participants to lead an independent clinical trial but does allow them to obtain research experience in a clinical trial led by a mentor or co-mentor.
