This initiative seeks applications that will explore person-specific characteristics, such as genetics, microbiome composition, and lifestyle, to improve the effectiveness of probiotic interventions and address variability in human responses. The total project period is limited to four years, with a maximum budget of $350,000 in direct costs per year, and applications are expected to include a Plan for Enhancing Diverse Perspectives (PEDP) to promote inclusivity.
