Many trillions of microbes live in our guts and elsewhere on our bodies. These microbes—the microbiome--contribute to health by helping with digestion, guiding growth of our immune systems, and shouldering out invading pathogens. People differ greatly in the composition of their microbiota, influencing us each in unique ways. The human microbiota has been reported to influence risk of heart disease, cancer, autism, obesity, inflammatory bowel diseases, and many other disorders. In the Bushman laboratory, we have studied the role of the human microbiome—bacteria, fungi, and viruses—in many of these disorders.
