Justin Sonnenburg, Ph.D., is currently an associate professor in the Department of Microbiology and Immunology at the Stanford University School of Medicine, where he studies the gut microbiota in health and disease and co-directs the Center for Human Microbiome Studies.

He and his wife Erica, are the authors of the book The Good Gut: Taking Control of Your Weight, Your Mood, and Your Long-Term Health. The goals of the Sonnenburg Lab research program are to (i) elucidate the basic mechanisms that underlie dynamics within the gut microbiota and (ii) devise and implement strategies to prevent and treat disease in humans via the gut microbiota.
