Erik Herzog studies the molecules, cells and circuits that underlie daily rhythms in physiology and behavior. He is the Viktor Hamburger Professor of Arts and Sciences at Washington University, past President of the Society for Research on Biological Rhythms, founder and Co-Director of the WU ENDURE Program, and Faculty Coordinator of St. Louis Neuroscience Outreach. With support from agencies including the National Institutes of Health and the March of Dimes, his lab has published over 100 peer-reviewed articles on topics including daily rhythms in pregnancy and its relevance to preterm birth and circadian rhythms in astrocytes and astrocytoma cells and how this impacts their sensitivity to intercellular signaling and chemotherapeutics.
