This document summarizes a lecture about analyzing the human microbiome and its relationship to human health. It discusses how the human body contains 100 trillion microbial cells that contain 100 times as many genes as human DNA. Analysis of the speaker's own gut microbiome over time revealed changes in bacterial phyla between healthy and inflammatory bowel disease states. Collecting biomarkers from the speaker's body over years showed oscillations linked to gut microbes and immune response. Ongoing research aims to better understand dynamics of the human immune system and gut microbiome.
