The Research and Mentoring for Postbaccalaureates (RaMP) in Biological Sciences program invites the submission of proposals to establish networks to support full-time research, mentoring, and training for recent college graduates who have had few or no research or training opportunities during college in research fields typically supported by the Directorate of Biological Sciences (BIO). A strategic focus of the National Science Foundation is to foster the growth of a globally-competitive and diverse research workforce. To that end, proposals submitted to this program are expected to create strong evidence-based, inclusive and culturally-aware mentorship programs that will advance the goal of creating a competitive and highly representative science, technology, engineering and mathematics (STEM) workforce in the U.S. with a focus on the biological sciences. Projects are expected to train individuals for a range of potential career pathways in the biological sciences including: research-focused M.S. or Ph.D. graduate programs; entry-level positions in industry, federal, tribal, or state agencies, education and research centers, or not-for-profit science-based organizations; or other STEM careers. Individuals from groups underrepresented in STEM, first generation college students, and students at under-resourced institutions frequently have limited opportunities to participate in the undergraduate research experiences that are necessary to be competitive for graduate programsorotherSTEMcareer pathways.This program will provide postbaccalaureate research experiences for cohorts of trainees, either in ongoing research programs, existing research networks, or in new research projects designed specifically for the RaMP networks. Studies of capacity-building and training across diverse disciplines have emphasized the importance of inclusive training via cohort mentoring and networks of individuals working together towards a common purpose. Cohorts promote the development of long-term relationships, and networks foster the exchange of ideas and resources to pursue common goals and to address shared challenges. Proposals will use a networkstructurethatgeneratesa supportive and strong collaborative mentoring environment centered around a cohesive biological research theme. The networks are expected to include diverse organizations and can be regional, national, or have an international component. The network will facilitate the recruitment and selection of postbaccalaureate research participants (hereafter, mentees) and mentors. Projects must provide inclusive and culturally-aware training to mentors in addition to providing professional development opportunities for all network members, including mentees, mentors, co-mentors, and other STEM professionals. Networks are expected to involve and facilitate communication and training among mentors and mentees from different organizations, institutions, and/or departments. Proposals submitted under this solicitation should focus on research-based inquiry projects that include analytical and technical training and professional development opportunities.
