PROGRAM SUMMARY/ABSTRACT The CTSA Predoctoral T32 Program at The University of Texas Health Science Center at San Antonio is the companion institutional training grant for postdoctoral research trainees. This Translational Science Training Program (TST) will provide 3 postdoctoral Trainees with innovative programing, assisting them develop those skills in team science, innovation, and scientific rigor necessary for a sustained career in Translational Science (TS). Research training in TS primes the next generation of translational scientists to become a highly skilled workforce that efficiently advances patient-focused research from preclinical and clinical settings to clinical implementation and population health arenas. Novel, innovative activities will increase TST training opportunities that fully leverage the unique strengths of local population health and data science (PHDS) investigators and resources (military, veteran, and Hispanic population data) together with CTSA community engagement teams. These and other key stakeholders will transform our existing TS practicum experience into a robust externship program that prepares Trainees to enter the TS workforce. TST (predoctoral + postdoctoral) Trainees, and K12 Scholars from UTHSCSA and Utah will meet quarterly in the CTS Roundtable to share ideas and strategies for successful team science. Upon program completion, postdoctoral TST Trainees will earn the graduate level TS Certificate. The TST T32 Program objectives are to: • Provide robust TS training for postdoctoral Trainees from early-stage translation and clinical disciplines • Emphasize research studies that address diversity, inclusion, and health disparities in Hispanic and military/veteran populations in our South-Central Texas region • Enable didactic and experiential activities that contribute to team science knowledge and skills • Expand the workforce of well-prepared TS investigators • Evaluate programmatic components for continuous quality improvement
