Kirsten Tillisch, M.D., an associate professor of medicine at the David Geffen School of Medicine at UCLA, explains how the microbiome in the gut takes care of us – and how we can take care of it. Tillisch is a pioneer in the study of microbe-gut-brain interactions, and is currently focusing on the role of mind-body interventions such as hypnotherapy, acupuncture, and mindfulness-based stress reduction for gastrointestinal disorders.
