The NGMP was established at UNL in 2008 as a collaborative facility to strengthen the efforts of microbiome researchers interested in understanding the factors, including diet, that shape the gut ecosystem. After a major expansion in 2020, the NGMP now maintains multiple strains of germ-free mice in a state-of-the-art facility capable of accommodating up to 50 flexible-film isolators, multiple high-density cage racks, and a positive-pressure Tecniplast ISOcage system. The NGMP has developed a strong reputation for success in maintaining a germ-free environment and completing large-scale, diet-focused microbiome experiments in mice, which has led to multiple local, national, and international collaborations and generated numerous publications.

Since 2012, NGMP efforts have been led by Dr. Amanda Ramer-Tait, who has over 20 years of experience working with germ-free and gnotobiotic mouse models. She has built a dynamic and internationally recognized research program that combines her training in biomedical research with personal connections to agriculture and food. Her research program aims to: (1) establish causality for the gut microbiota and its metabolites in health and disease, (2) identify diet-microbiota interactions that improve disease outcomes, (3) design microbiome-based strategies for treating disease, and (4) advance the use of gnotobiotic mouse models for microbiome research.
