Federal Grant Award Summary

The National Institute of General Medical Sciences (NIGMS) awarded the University of Wisconsin–Madison a $418,331 Project Grant effective July 1, 2026, through May 31, 2031, under the Biomedical Research and Research Training program (CFDA 93.859). This award supports the development of advanced statistical methods for microbiome data analysis to address critical methodological challenges in large consortium-based microbiome studies. The project will deliver three primary products: innovative batch-effect correction methods to standardize data across disparate studies, meta-analysis techniques to integrate findings at scale, and robust causal-inference tools to establish mechanistic relationships within microbial communities. Additionally, the award funds the development and dissemination of user-friendly, open-source software to operationalize these methods and maximize their adoption across the research community.

The underlying objective is to improve the reproducibility and clinical translation of microbiome research by resolving analytical obstacles inherent to microbiome data, including compositionality, high variability, and extensive heterogeneity. By enhancing the efficiency and reliability of microbiome discovery, the project aims to deepen understanding of the microbiome's role in complex disease onset and progression while accelerating the development of microbiome-based precision medicine strategies for prevention, diagnosis, and treatment.
