Exploring the Microbial Cosmos
The human body is home to countless microbes. The intestinal tract, in particular, is colonized by innumerable bacteria. As a young environmental microbiologist, Ruth Ley never imagined that she would one day find herself interested in the human gut and the microbiota that reside in it. Today she conducts research at the Max Planck Institute for Developmental Biology in Tübingen, investigating the role the countless intestinal bacteria play in our health.
