Andrew W. McHill, Ph.D. (he/him)

  • Assistant Professor, School of Nursing
  • Assistant Professor, Oregon Institute of Occupational Health Sciences
  • Assistant Professor of Graduate Programs in Human Nutrition, School of Medicine


Dr. McHill graduated with a Ph.D. in Integrative Physiology with a specialization in sleep and circadian physiology from the University of Colorado Boulder. After graduating, he completed an NIH funded post-doctoral fellowship at the Brigham and Women's Hospital and Harvard Medical School within the Division of Sleep and Circadian Disorders and joined the OHSU Oregon Institute of Occupational Health Sciences in Dr. Shea's Circadian Laboratory in 2016 as a visiting post-doctoral fellow. In September 2017, he became a Research Assistant Professor within the institute and in 2021 established the Sleep, Chronobiology, and Health Laboratory within the OHSU School of Nursing as an Assistant Professor. Dr. McHill is interested in understanding the contributing mechanisms by which the mistiming of behaviors (i.e. shiftwork or jetlag) and chronic insufficient sleep leads to adverse health and poor cognitive performance outcomes.
