Circadian clocks, which drive circadian rhythms, are entwined with many essential systems in living things including plants, fungi, insects, and even humans. Because of this, disruptions to our circadian clocks are linked to higher disease rates in humans, including certain cancers and autoimmune diseases. Rensselaer Polytechnic Institute’s Jennifer Hurley, Ph.D., Richard Baruch M.D. Career Development Chair and Associate Department Head of Biological Sciences, has dedicated her career to understanding the mechanisms that allow our circadian clocks to keep time.
