As a result of 3.5 years of successfully awarding and supporting developmental projects (3 cohorts), mentoring new investigators, and other supporting activities as a D-ARC, the Dev Core proposes to extend our work as a Full ARC, building and sustaining the growth of investigators pursuing mental health (MH) and HIV research. The focus continues to be on community engaged research mitigating the disparities experienced by populations living with HIV. The Dev Core Awards Program will support Early Stage Investigators (ESI), established investigators new to MH/HIV, and community stakeholders, in pursuing community-engaged, MH/HIV research focused on mitigating health disparities. We will offer traditional Pilot Awards, Scholar Awards that emphasizes research skills development and investigator time for research, Community Pilot Awards in partnership with the MHD-CE Core, and Program Planning Micro-Grants in partnership with the EIS Core. We will expand eligibility for the Pilot and Scholar Awards to investigators from other regional institutions: Florida State University, Florida International University, Nova Southeastern University, and University of Central Florida. At least one Pilot or Scholar Award each year will be implementation science-focused, with priority areas informed by the EIS Core. The Dev Core coordinates the review of each award, and we systematically track and support the progress of awardees and support those who are not selected in revising their proposals for future funding mechanisms. The comprehensive mentoring program encompasses our efforts to support the career development of ESI. We facilitate the efforts by assembling a mentoring team (through the Mentoring Advisory Committee) and pursue comprehensive individual development plans (IDP). Career development of ESIs is further supported by our contributions to ongoing career development and grant writing workshops in synergy with other Cores and research Centers at UM and beyond.
