MSU biochemist Robert Quinn’s recent discovery related to bile acids produced by gut microbes represents a paradigm shift of 170 years of research in the field. Quinn, an assistant professor in the Department of Biochemistry and Molecular Biology in the College of Natural Science, received a one-year, $100,000 grant from the Global Grants for Gut Health to dig deeper into this discovery and how it changes scientists’ understanding of the human gut microbiome.
