The University of Arizona Sleep and Development Lab studies environmental and behavioral factors affecting sleep and circadian health in children and adolescents, including light exposure, screen media use, and melatonin supplements.
We utilize measures of behavior (actigraphy, cognitive tests, sleep and media diaries) and physiology (salivary melatonin, pupillometry) to answer fundamental questions about children’s circadian physiology, as well as to develop and test interventions to improve young children’s sleep and circadian health.

Lab Members
Lauren E. Hartstein, PhD
Lab Director
laurenhartstein@arizona.edu
Dr. Hartstein is an Assistant Professor of Psychiatry at the University of Arizona College of Medicine. Dr. Hartstein completed her B.A. in Psychology at Vassar College and her M.S. and Ph.D. in Developmental Science at the University of Massachusetts Amherst. She received training in the non-visual impacts of the lighting environment at the Lighting Enabled Systems & Applications Center at Rensselaer Polytechnic Institute. She then completed a postdoctoral fellowship in child sleep and circadian physiology with Dr. Monique LeBourgeois at the University of Colorado Boulder. Her research interests are focused on questions of how the modern built environment impacts children’s sleep and circadian rhythms across development. Dr. Hartstein’s research has been supported by the National Institutes of Health and the American Academy of Sleep Medicine.
Sherap Sangpo
Clinical Research Coordinator
sangpo@arizona.edu
Sherap is a Clinical Research Coordinator for the Circadian Light Exposure Adjustment for Restfulness (CLEAR) and EBB/FLOW studies. He earned his B.S. in Psycholgoical Science from the University of Arizona, where he was an undergraduate member of the Sleep and Health Research Program for three years. He plans to complete a Master’s in Clinical Translation Science at the University of Arizona before applying to MD-PhD programs. In his role, Sherap enjoys solving problems across diverse studies and is particularly interested in translational science and the process of developing interventions. Outside of the lab, he spends time outdoors with his two doodle and enjoys running, biking, and working on hobby coding projects.
