Research Interests

  • My research is focused on understanding how circadian rhythms function to influence the timing of physiological and molecular processes, and how this control is impacted by disease. Our current research involves uncovering the link between circadian rhythm disruption in neurodegenerative diseases, such as Alzheimer's disease, as well as in addiction.
