In this episode, I speak to Rob Knight, an assistant professor in the Department of Chemistry and Biochemistry at the University of Colorado, Boulder.

Knight studies our inner ecology: the 100 trillion microbes that grow in and on our bodies. Knight explained how hundreds of species can coexist on the palm of your hand, how bacteria manipulate your immune system and maybe even your brain, and how obesity and other health problems may come down to the wrong balance of microbes.
