PROJECT ABSTRACT For more than 20 years, the American Gastroenterological Association (AGA) has successfully executed NIDDK-funded efforts to promote the recruitment and retention of underrepresented physician-scientists in gastroenterology. Our Fostering Opportunities Resulting in Workforce and Research Diversity (FORWARD) Program was first funded in 2018 and has successfully recruited and trained numerous senior and near-peer mentors who have effectively guided early-stage professionals toward grant funding, academic promotions, and leadership roles within AGA committees. The current FORWARD Program enrolls and trains cohorts of 14 scholars over an 18-month training period. However, since its inception, FORWARD has become a top-rated program for training for early-stage underrepresented gastroenterologists with a proven track record of successful career outcomes among program alumni. Thus, interest from the gastroenterology community has far exceeded the availability of training slots, creating a new challenge for AGA in 2024. Our proposed supplemental application, the Best of FORWARD immersion experience, is designed to disseminate the most impactful aspects of the longitudinal FORWARD experience for a larger audience that cannot be accommodated through the parent program. Similar to the parent program, our overall objective is to overcome a primary impediment to diversifying the biomedical workforce -- accessible and effective mentorship. We plan to accomplish our objective through four specific aims: 1) Enhance mentorship through access to race and ethnicity-concordant near-peer and senior mentors. 2) Broaden academic research skills. 3) Strengthen leadership skills with a focus on team science and lab management. 4) Establish a sustainable network of underrepresented physician-scientists and mentors through a digital community within a mobile app.
