Jessica Finlay Publishes New Popular Science Book: The Microbiome Master Key

The Microbiome Master Key

Assistant Professor Jessica Finlay and her co-author father Dr. Brett Finlay published The Microbiome Master Key: Harness Your Microbes to Unlock Whole-Body Health and Lifelong Vitality. In this popular science book, they explore how microbial communities everywhere in and around us impact your brain health, sleep, immune system, metabolism, and more. The work bridges Jessica’s expertise in geographies of aging with microbial science to demonstrate how social, spatial, and environmental factors connect to invisible ecosystems within and on our bodies. It also weaves personal narratives—including stories of cross-generational scientific collaboration—into the science, making complex research accessible through family, science, and place.
