Dr. Sabine Hazan has spent her career studying a part of the body most people never think about until something goes wrong: the gut microbiome. A gastroenterologist and researcher, she has built much of her work around the trillions of microbes that live in the digestive system and the role she believes they play in human health. When Dr. Sabine Hazan joined Sean Kelly on the Digital Social Hour, the discussion turned the spotlight on a field that is still rapidly evolving.
What follows is a science-forward conversation in which Hazan walks through her research, her hypotheses, and the questions she finds most pressing — presented throughout as her own perspective on where microbiome medicine may be heading.
