Persephone Biosciences, based in San Diego, operates in the biotechnology research field with a focus on the microbiome and its impact on infant and patient health. Founded in 2017 by synthetic biologists Stephanie Culler, Ph.D., and Steve Van Dien, Ph.D., the company pursues research-led development of next-generation probiotics and therapeutics, including a synbiotic designed for infants and toddlers to support gut and immune health from early life. The company collaborates with healthcare organizations and industry partners to translate microbiome science into clinical and translational opportunities, including work with Janssen on colorectal cancer risk studies and with Kroger Health on related clinical investigations. It launched the My Baby Biome study in 2022 to investigate infant gut dysbiosis and its potential links to long-term health outcomes. In October 2023, Persephone completed its first collaboration with Ginkgo Bioworks to develop a Bacteroides engineering toolkit.
