The National Institutes of Health (NIH) is offering the Maximizing Opportunities for Scientific and Academic Independent Careers (MOSAIC) Postdoctoral Career Transition Award (K99/R00) to promote diversity within the biomedical research workforce. This funding opportunity is designed for early-career investigators from underrepresented backgrounds, providing a structured pathway to transition from mentored postdoctoral roles to independent faculty positions, with a focus on basic experimental studies involving human participants. The program consists of two phases: the K99 phase allows for up to two years of mentored career development, while the R00 phase provides three years of independent research funding, contingent on satisfactory progress. Interested applicants must demonstrate contributions to inclusivity in research and have no more than four years of postdoctoral experience. The application deadline is September 7, 2027, and further inquiries can be directed to NIH Grants Information at grantsinfo@nih.gov.
