Dr. Davis received a BS in nursing from Michigan State University; a MS in nursing as a clinical nurse specialist from Hunter College, the City University of New York; and a PhD in clinical nursing research with a major in physiology from the University of Arizona. 


Examples of courses taught include:

  • Adult Health Nursing
  • Nurse Scientist Role
  • Research Methods
  • Biomarker Measurement
  • Biological Basis of Sleep 


Dr. Davis’ research program focuses on the study of sleep and circadian rhythm disruption in vulnerable populations and the effects of nonpharmacological interventions to improve sleep.  Vulnerable populations studied include postmenopausal women, women with breast cancer undergoing chemotherapy, women with Alzheimer’s dementia, patients with cardiac disease receiving left ventricular assist devices, young adults with asthma, women who are obese, and homeless women.  Nonpharmacological interventions studied include exercise, therapeutic bright light, yoga, and cognitive behavioral therapy for insomnia.    


Dissemination activities have included over 90 national and international scientific podium and poster presentations at the Midwest Nursing Research Society, Southern Nursing Research Society, Oncology Nursing Society Congress, National State of the Science Congress, International Conference of the Society for Integrative Oncology, Annual Scientific Meeting of the Obesity Society, American Heart Association Scientific Sessions, Associated Professional Sleep Societies Meeting, International Society for Behavioral and Cognitive Disorders, American Academy of Otolaryngic Allergy, and Gerontological Society of America.
