Principle Investigator
Dayna Johnson, PhD
Dr. Johnson’s research is aimed at understanding the root causes of sleep health disparities and their impact on cardiovascular disease by 1) addressing the social and environmental determinants of sleep disorders and insufficient sleep; and 2) investigating the influence of modifiable factors such as sleep disorders and disturbances on disparities in cardiovascular outcomes.

External Collaborators
Donald Bliwise, PhD
Emory University
Donald Bliwise, PhD is a Professor in the Department of Neurology, Emory University School of Medicine, where he is Director of the Program in Sleep, Aging and Chronobiology. His program of research focuses on the description, elucidation of mechanism, and treatment of sleep and related disorders in aged populations. He has extensive experience as a research and industry consultant for multiple agencies and federally funded investigations. He is board certified in Sleep Medicine and maintains licensure as a clinical psychologist
Helen Burgess, PhD
University of Michigan
Dr. Helen Burgess is originally from Australia, where she completed her undergraduate and graduate degrees. She is now a Professor at the University of Michigan in Ann Arbor and Co-Director of the Sleep and Circadian Research Laboratory in the Department of Psychiatry. Her current research focuses on the assessment and treatment of sleep and circadian disturbance in a variety of human clinical conditions including alcoholism, chronic pain conditions, diabetes, depression, HIV, and post-traumatic stress disorder. She enjoys spending time with her family and two cats, nature hikes and traveling.
Gena Glickman, PhD
Uniformed Services University of the Health Sciences
Dr. Gena L. Glickman is an Assistant Professor of Psychiatry and Neuroscience at Uniformed Services University in Bethesda, Maryland. She received Bachelor Degrees in Psychology and Occupational Therapy from Villanova University and Thomas Jefferson University, and a Masters and Doctoral degree in Experimental Psychology from University of California, San Diego (UCSD). Prior to starting at USU, she continued at UCSD as a faculty member in the Center for Circadian Biology and also began conducting military research at the Naval Health Research Center in San Diego, California. Dr. Glickman has broad expertise in behavioral neuroscience and circadian rhythms, and the primary focus of her research program is to further understand sleep, circadian rhythms and the biological effects of light in order to maximize human health and well-being. To that end, she has studied the effects of different lighting characteristics (e.g. exposure parameters, prior light history) on circadian resetting, melatonin suppression and the efficacy of therapeutic applications. By employing a variety of biomedical research techniques in humans and rodent models, her work has further elucidated the neural mechanisms that mediate the biological effects of light. Dr. Glickman’s lab is now examining how the basic science of this primitive sensory system can be used to guide the rational development of clinical therapies and architectural lighting strategies. Current applications under investigation include the use of light therapy as an adjunct to cognitive processing therapy for patients with post-traumatic stress disorder and major depressive disorder as well as novel, multi-component lighting interventions that aim to optimize health and performance in hospital shiftworkers and military service members.
Roby Greenwald, PhD
Georgia State University
Dr. Greenwald’s primary research interests are measuring the ways in which air pollution influences human health. Since joining the Department of Environmental Health in 2009, much of their work has involved the development of unique sampling systems for assessing exposure to air pollution in special microenvironments such as inside vehicles while commuting. From 2005 to 2008, they were a post-doctoral fellow in Emory’s Department of Pediatrics and worked on a project investigating the influence of air pollution exposure on pediatric asthma patients. From 1999-2005, they were a PhD student at Georgia Tech and worked on two projects: development of an instrument to measure water-insoluble aerosols in real-time and computer modeling of the influence of atmospheric particulate matter on crop production. Prior to graduate school, they were a Peace Corps Volunteer in Benin, West Africa (1995-1998) and studied civil engineering at Clemson University (1990-1994). They are currently an Assistant Professor at Georgia State University.
Kristen Knutson, PhD
Northwestern University
Dr. Knutson’s research focuses on the association between sleep, circadian rhythms and cardiometabolic diseases, including diabetes, obesity and cardiovascular disease. They focus on real world assessments of habitual sleep patterns and perform detailed clinical measures of biomarkers of disease risk. In addition, their research examines whether sleep and circadian rhythms partially mediate socioeconomic and/or racial/ethnic health disparities.
Tené Lewis, PhD
Emory University
Tené T. Lewis’ primary area of research is in the area of health psychology/psychosocial epidemiology, with an emphasis on cardiovascular health in women. She has a particular interest in understanding how psychological and social factors contribute to the disproportionately high rates of cardiovascular disease morbidity and mortality observed in African-American women compared to women of other racial/ethnic groups. Dr. Lewis has two primary projects: one focused on psychosocial stress, resilience, and ambulatory blood pressure in healthy African-American women, and the other focused on psychosocial stress, inflammation and atherosclerosis in African-American women with Systemic Lupus Erythematosus. Dr. Lewis’ scientific work has received honors from the American Psychosomatic Society and the Health Psychology Division of the American Psychological Association and has been featured in the Washington Post, USA Today, Essence Magazine, JET magazine and on National Public Radio (NPR).
