Your body's microbiome are the bacteria, fungi, archaea and viruses living inside you along your own human cells. Surprisingly, there are more microbiota in your body than your own cells! David Hachuel is a Health Tech Master's Student at Cornell Tech and has researched how your body has evolved with the microbiota in it. We talk about the human body's ecosystem and how his startup, Auggi, is using Artificial Intelligence to help people keep track of their diet and how that diet affects their health and poop.
