Sleep Medicine Faculty

Christopher L. Drake, PhD

Director of Sleep Research

Dr. Drake is a licensed clinical psychologist, former Chairman of the National Sleep Foundation, former keynote speaker at the Michigan Association of Sleep Medicine, and current Director of Sleep Research at Henry Ford Health, Adjunct Associate Professor at the University of Michigan, and Professor at the Wayne State University College of Medicine. With decades of experience, he has developed a broad clinical background with specific training and expertise in sleep medicine, successfully completing multiple longitudinal studies. His scientific focus has been to understand the psychological, environmental, and physiological factors that predispose individuals to insomnia, and he strives to improve sleep health by increasing access to behavioral treatment of insomnia. He is currently funded by the National Institutes of Mental Health (NIMH). Dr. Drake’s primary contributions to science include:

  • Impact of insomnia on daytime functioning, mental health disorders, and medical comorbidities
  • The relationship between sleepiness and car accidents: Links between a physiological measure of sleepiness and police-verified automobile accidents, providing a measure of risk
  • Sleep reactivity: Investigations of this trait’s existence, development of a measure for it, and studies of its heritability and relationship to insomnia predisposition and depression
  • Numerous behavioral, pharmacological, and device-related clinical trials in sleep medicine
  • Impact of rumination and cognitive arousal on sleep, insomnia, and Major Depressive Disorder

Dr. Cheng has cultivated a program of research focused on the clinical translation of circadian science into practical and widely accessible tools and interventions. His primary contributions to science include investigations into:

  • Sleep and circadian rhythms in mental health: How disruptions in sleep timing and quality impact symptoms of Major Depressive Disorder.
  • Behavioral treatment of insomnia: Impacts of digital delivery of Cognitive Behavioral Therapy for Insomnia (dCBT-I) across a range of demographic groups, and the effect of socioeconomic disparities on treatment completion.
  • Rumination and cognitive arousal as contributors to poor health.
  • The relationship between sleep and stress: Importance of sleep in stress regulation
  • Sleep in health disparities populations: Disparities in insomnia and other health conditions as a result of racial discrimination.
