The NIH Research Education Program (UE5) supports research education activities in the mission areas of the NIH. The over-arching goal of the MOSAIC UE5 program is to support educational activities that encourage individuals from diverse backgrounds, for example those from groups underrepresented in the biomedical and behavioral sciences, to pursue further studies or careers in research. To accomplish the stated over-arching goal, this FOA will support creative educational activities with a primary focus on Courses for Skills Development and Mentoring Activities. Applications are encouraged from organizations of biomedical researchers (e.g., scientific societies) with a membership of scientists conducting research within the mission of NIH, experience serving as a centralized entity to enhance scientific communication and networking among scientists conducting research, an established record of providing professional development and networking activities for the next generation of biomedical researchers, and a demonstrated commitment to enhancing the diversity of the biomedical research workforce. The program provides support for well-designed courses for skills development and mentoring activities to prepare MOSAIC K99/R00 grantees to transition into, succeed, and advance in independent faculty careers at research-intensive institutions.
