The purpose of the Advancing Research Careers (ARC) Predoctoral to Postdoctoral Transition Award to Promote Diversity (F99/K00) program is to support promising, late-stage graduate students from diverse backgrounds to transition into and succeed in mentored postdoctoral research positions. The program aims to position ARC scholars to advance in impactful careers in the biomedical research workforce that typically require postdoctoral training. Some key points about this opportunity include: • The program provides support for late-stage graduate students pursuing research related to the mission areas of participating NIH Institutes, Centers, and Offices (ICOs). • The two-phase award includes the F99 phase for doctoral dissertation projects and research training, and the K00 phase for postdoctoral biomedical research and career development opportunities. • ARC F99 fellows/K00 scholars will be part of organized cohorts and will be expected to participate in mentoring, networking, and professional development activities coordinated by ARC Institutionally-Focused Research Education Award to Promote Diversity (UE5) recipients. • Eligible applicants include various types of organizations, such as state governments, city or township governments, public housing authorities, and non-profit organizations.
