PROJECT SUMMARY This revision application to the UCSF-Bay Area CFAR aims to strengthen our support for diverse HIV researchers or investigators who study disparities in HIV and foster investigators from the pipeline (undergraduate/masters’ level students) to early career faculty, all through revisions to our Developmental Core. Key initiatives include the CFAR Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI) Scholars’ program, a mentored summer research internship for undergraduate/masters’ level students from a historically minority-serving institution in San Francisco (Aim 1); a mentoring training program for underrepresented early career investigators or those who study health disparities (Aim 2); and a career development award program for faculty working with diverse populations or from underrepresented minority backgrounds (URM) (Aim 3). The application’s overarching goal is to formalize and integrate successful diversity initiatives into the Developmental Core, ensuring our sustained impact on creating a pipeline of investigators who can contribute to ending the HIV Epidemic. Our work proposes three aims. The first aim is to sustain and expand the CFAR Scholars Program, providing mentored research experiences for local minority-serving institution students, particularly from underrepresented backgrounds. We aim to leverage our mentoring infrastructure and emerging URM mentors to make this a lasting program within our CFAR. The second aim is to support and train underrepresented early career investigators in mentoring through the Mentoring the Mentors training program. This program, specifically targeted to URM postdoctoral fellows and early career faculty, should improve mentor and mentee outcomes and promote career development. Trainees in this designated mentoring program will be drawn from our URM Mentoring Program, mentors of our CFAR Scholars (Aim 1), and the Inter-CFAR URM Working Group we organize. Our final aim is to formalize the CFAR/ARI Career Development Program, supporting early career faculty from URM backgrounds or working with diverse populations. This program, previously known as the Diversity Scholar Award, has significantly contributed to the success of past awardees, aiding in grants, publications, and retention. Each of these programs will be subject to rigorous tracking and evaluation of outcomes and will be enhanced through repeated feedback cycles detailed in our Plan for Enhancing Diverse Perspectives. Through these aims, we seek to build a diverse workforce, enhance mentoring capabilities, and provide critical support for diverse early career faculty. These efforts align with the goals of the funding announcement by addressing disparities in HIV research, fostering inclusivity, and contributing to improved health outcomes for individuals living with HIV.
