This document discusses Dr. Larry Smarr's research into understanding the relationship between the human immune system and gut microbiome in Crohn's disease. Dr. Smarr sequenced his own genome to identify genetic polymorphisms associated with higher risk of Crohn's disease. He also conducted fine-time resolution sampling to study the distinct dynamics of the innate and adaptive immune system in health and disease. Additionally, he found major shifts in the gut microbiome between healthy individuals and those with two forms of inflammatory bowel disease.
